The streaming, no pun intended, comes from EroticVision.TV. The company will deliver a number of channels to your Roku player, but for now all we know of is "Wasteland.com." For the unfamiliar, that's a BDSM website.

Parental controls will bar yougins from seeing any BDSM tomfoolery, and to access the content you'll have to register your box with EroticVision.TV. Uh, enjoy? Update: NSFW porn is obviously redundant. "Changed." [CrunchGear]

The relevant passage from the FT:

Apple has contacted other broadcast and cable networks, including Time Warner's Turner Broadcasting System and Viacom, which have so far been unconvinced by Apple's proposal. The computer maker has also courted the book publishing industry, sector executives say.

Cooperation with Time Warner and Viacom would be essential if Apple wants to get this cable replacement off the ground—they own a plurality of basic cable channels between them. As far as the tablet is concerned:

Apple is preparing an announcement next month that many anticipate will be the official unveiling of its tablet, but the company has so far declined to confirm the existence of the device. Wall Street analysts expect mass production of an Apple tablet to begin as early as February.

That's some serious confidence right there, but it lines up with what we heard yesterday. This is all speculation at this juncture, but the WSJ and FT are big dogs who can (for the most part) be trusted; we'll have to see whether 2010 really is the year of the tablet. [Financial Times]

The WSJ says that Apple's plan for iTunes TV show subscriptions would have you pay a monthly fee for "access to some TV shows from a selection" of major networks, and that CBS and Disney are the two most seriously thinking about it. CBS would apparently offer up shows from both CBS and the CW, like Gossip Girl, while Disney would be offering up shows from ABC, ABC Family and the Disney Channel. What's interesting is that the networks could actually make more money per subscriber than they do from cable companies, with broadcast networks picking up $2-$4 per subscriber, and cable networks grabbing $1-$2. (Which has to piss cable companies off, no doubt why networks are treading carefully around this proposal.) Originally, Apple had floated something more like a traditional cable payment, like paying $30 a month for a big bundle of TV stuff.

All of this, of course, would fit into Apple's larger plan to remake the iTunes model with Lala, and Apple hopes to launch the service sometime next year. While the way Apple says songs and TV shows now would stick around according to the Journal, the combination of web-and-streaming-oriented music and TV subscriptions fundamentally changes the way iTunes would work.

Oh, and of course, this is all happening as Apple "finalizes its plans for a tablet device," Apple's trying to launch "by the end of March." Interesting, that's what an analyst heard not too long ago. Killing cable and up-ending the publishing industry in one fell swoop? That's a pretty busy 2010. [WSJ]

The winter months are the hardest time to not want new stuff. We're inundated with sales, and in a few short weeks we'll be ogling next year's tech at CES. As the resident Gizmodo "no I won't upgrade my PowerBook" curmudgeon, I'm here for support. Take a look at the gear I use, and how despite its age, all (well, most of) it has plenty of life left.

I Call Him FrankenPod

No, you're not seeing things. The image above is indeed a picture of my primary media player, and yes, it is an iPod mini.

Go ahead, get the Borat jokes out of your system.

Done? Okay, now hear me out. Don't judge a book by its cover. As far as I'm concerned, this little guy can blow away nearly any other MP3 player on the market.

Under the hood, I swapped the 6GB microdrive with a 16GB Compact Flash card. I can easily change it out for a 32 or a 64GB card once prices come down. It's also running what I consider to be the most feature-rich firmware around, Rockbox. What looks like a beat-up iPod mini is actually a robust, nearly indestructible flash-based portable audio player, all built for a fraction of what a new one costs.

The mini isn't the only old iPod that's easily moddable. Considering about 118% of the United States' population has an old iPod lying around somewhere by now, chances are you've got what you need for a fun weekend project. Even if your heart's set on the Zune HD's OLED display or the Touch's app catalog, some love and a little elbow grease can breathe old life into that old iPod, and give you a great secondary PMP.

The Little Computer that Could

When I walked into Gizmodo HQ on my first day, I was nervous. Some of that anxiety was the new job jitters, but I was mostly afraid that my 12" PowerBook wouldn't cut it. Gizmodo moves fast, and my aging machine certainly doesn't. I was on the verge of upgrading, but decided to see how my old hardware fared before taking the plunge.

Long story short: It did the job. Barely. But through compromise, I made it work. I love Firefox and all of its extensions, but Safari runs at half the resource load. Photoshop Elements does what I need without the huge footprint of CS. With a little thought as to what applications I was running, which ones I didn't need, and where I was willing to compromise, my plucky PowerBook and I made it through the summer.

As much as I love the little guy, it's not like I haven't thought about replacing him. I almost pulled the trigger on a new MacBook last month. At the last minute I decided that instead of buying a computer that would last me 2-3 years, I wanted another that could feasibly last for 4+. Whenever that computer comes out, I'll probably bite, but until then I'm happy squeezing a little extra life out of my aging hardware.

Look at how you use your computer. If you're rendering all day, never leave Photoshop, or doing any other heavy computing and you need the speed, then upgrade. But the rest of us can probably hold off a little longer, even tech-obsessed gadget bloggers.

Nice Peeling Chrome Paint, Dude

I'm fairly certain I'm the only writer at Gizmodo without a smartphone. Yes, dumbphones must die, and someday I will upgrade this one. But for now, it makes calls, texts, and even has an almost acceptable music player built in that works in a pinch. Google services run surprisingly well in a WAP browser, too, so I can get email and read my RSS feeds when necessary.

Would I love to have a smartphone? Sure. (Hey Brian Lam and Jason Chen, skip down a few sentences) But it's also really nice to be disconnected sometimes. My Gizmodo email account receives a very steady stream of emails, to say the least. I like being able to walk away from the computer and cut myself off every once in a while, without my phone constantly reminding me that there's work to be done (Okay overlords, you can read on from here).

Just Because it's Old Doesn't Mean it Sounds Worse

No, this stereo doesn't do DTS-HD Master Audio. It has zero HDMI ports. But it still does 2-channel audio pretty well, more than well enough for what I need it to do.

Repurposing old stereo equipment is one of the best ways to build a great system on the cheap. The turntable and receiver are my dad's old gear, coupled with a pair of speakers I yanked off of a CD player I've had since I was 14. The setup won't win me any audiophile cred, but it definitely does a much-better-than-OK job at playing music.

Not to mention that it's pretty cool to listen on the same equipment my dad once used. When I was 17, I found his old record collection in the basement and immediately started spinning it on his long-forgotten turntable. Call me corny, but I think it's pretty awesome to know that 30-some years ago he was listening to the same records on the same deck.

If you aren't lucky enough to have access to your parents' old stereo equipment, it's not uncommon to find some real gems at your local thrift shop on the cheap, tossed away by someone who thought McIntosh is a cheap Apple knock-off.

Okay, so Maybe I Want to Upgrade Some of It

I do have one thing that I desperately want, and will upgrade to soon: an HDTV. I've never owned anything besides tube TVs under 20 inches. The fact that flat-panel prices are finally reasonable, combined with the digital switchover makes it prime time for me to jump the CRT ship.

I want to say that it always makes sense to hold onto your old TV after you upgrade, but in this case it might not. Television sets were at their saturation point well before HDTVs came along. In 2009 there were more TVs per household than people. By now it's likely that you just don't have room for a fourth or twelfth tube anywhere.

If you find yourself needing to dispose of an aging TV, please do so properly. Donate it. Sell it on Craigslist. Or look into electronics recycling centers in your area. An old TV may not have a place in your house or apartment, but it might find a place in someone else's home. It certainly doesn't belong in a landfill.

See? I'm Not a Total Luddite

I might roll with old stuff, but I'm not some sort of quasi-neo-luddite. Plenty of other gadgets in my arsenal are much more recent than what you see here. I have a PS3, my music gets fed to my stereo through a Squeezebox, and I do have another receiver that handles multichannel audio, albeit a relatively cheap and older one (and in case you're wondering, I did take these pictures with a DSLR, but it's not mine).

So yes, even I don't always live by the "never upgrade" mentality. Planned obsolescence and the industry's fast pace make it impossible to live by that creed. But I also think that a lot of the time we feel "forced" to upgrade we're really being driven by gadget lust, that powerful desire which makes us overlook the benefits of using old stuff.

Here's what I always think about when that ol' familiar "gotta have it" feeling hits. The biggest and most obvious perk: buy new stuff less often, save money. I don't know about you, but if I walk away from a big purchase, I feel like I've won. It's like trapping money that was trying to escape from my bank account. And if you've got a bit of the tree-hugging hippy spirit in you, you'll feel good about cutting down on your e-waste output, even if only by a little bit.

Not to mention the freedom old gear provides. I imagine it's similar to the feeling of operating the Mars rovers. I know that my gadgets have gone far beyond their planned mission length, so I throw them around without caring if they get damaged. And once that old gear inevitably goes belly up, I'll feel no remorse upgrading something that lasted for so long.

But that doesn't mean I won't be sad to lose my gadgets. I've heard other tech junkies say that we should never fall in love with technology, because we'll just end up heartbroken when it's time to say goodbye. In my opinion, that emotional connection is exactly what we need nowadays. If we all try to love our gadgets, to start treating them more like companions than disposable tools, a lot more perfectly good gear could be saved from an untimely retirement.

I know more than a few of you out there are eyeing some new toys for the holidays. I am too. But before we let upgraditis get the best of us, let's consider what we already have. Maybe it's still good enough. Maybe there's a new part that could make our gadgets better and provide a fun modding project to boot. Take it from me: There's almost always some way to squeeze extra life out of old gear.

Now, if you'll excuse me, there's an old Dell tower around here somewhere that's begging to become a NAS.

The Price

$150 as tested, for a 40-42" screen.

The Verdict

If you had a very nice TV and a very naughty child, I could see the appeal of TV armor.

The hardest part of installation is pulling the plastic film off the TV armor itself. Once that's done, you stick a few felt adhesive pads on the back, then set the armor directly over your television (it hooks from the top).

Even without the straps, I found the shield extremely well-balanced. That is, before I proceeded to bang the crap out of it with my remote. I basically tried to stab my Samsung to death with a blunt DirecTV remote. And I failed (which was a good thing).

While I'm not sure it could withstand a brick coming straight at it, TV Armor didn't flex enough to contact my TV's real glass screen at all during my remote test. However, the armor wasn't left completely unscathed. Some of the remote's plastic left little spots on the screen (and items like keys are sure to scratch the surface). But, I guess if you were investing in the product, you'd want it damaged rather than your TV.

As for glare and general watchability, it roughly doubles reflections coming off the screen. I found the sacrifice adequate, though depending on your precise lighting situation, results may vary. (The glare off a fully open window can get pretty intense at certain angles.)

So it's your call. But if I may be as bold as to suggest, for $130, the money spent on TV Armor could buy a lot of Ritalin and child muzzles. [TV Armor]

Solid construction

Minimal effects on overall image quality

Once it scratches, does that defeat the point or completely justify the device?

Increases glare moderately

All that's known about it is that it's 802.11b/g wireless-compatible and connects to a TV. Curiously, it's been filed under the 'display devices' category, for 'televisions, monitor, picture frame.' Any thoughts? A Wi-Fi adapter for Sony Bravia TVs? Something which will let you use your PS3 wirelessly? An adapter for flashing up a message on your Bravia, alerting you to the fact that your Sony Ericsson phone has finished charging? Answers on a postcard, please. [FCC via Sony Insider via Engadget]

I read your story on falling TVs yesterday, and I wanted to show you this picture of me, age four. That's when a TV tried to kill me.

I was simply trying to put the remote back on top of our 27" wood console Magnavox television, when I slipped while climbing onto the TV cabinet.

Instead of just falling to the ground, I grabbed the top edge of the Magnavox as I tumbled down to the ground. I hit the ground first, then the TV followed with one of the corners squarely landing on my forehead. The television slid off my head, taking about a quarter of my scalp with it.

The babysitter—my parents were at the movies—described it as "if someone had opened my scalp like they would open a banana peel." I ran around the house screaming in shock, but the babysitter—who later became my mother's best friend—did everything right, kept her calm, and called 911.

One hundred and forty-four stitches later, and enough hospital ice cream to please any 4-year-old boy, I was on my way to a steady recovery. I had some temporary nerve and muscle damage that affected things like my eyebrows, but I was lucky enough to have no long-lasting damage that I'm aware of. I'm obviously incredibly lucky that I've been left unscathed short of a very large scar across my forehead. As you know, there are many other people that haven't been as lucky.

I would love it if you could post my story and my picture in Gizmodo. It would be great if my story can help make other people aware of the significant dangers of untethered CRTs or flat screen TVs.

Thanks Russell. Hopefully, this will make more people aware of this problem.

Putting its money where its mouth is, LG's also joined forces with the Korean SkyLife, one of the largest 3D TV broadcasters in the world. Aiming to create industry standards, and do for 3D TV what Sony did for Blu-ray, they'll work together to ensure those ambitious sales targets are met.

Ultra-slim bezels are part of LG's hook, which supposedly help the 3D image pop with more effect. No doubt we'll be seeing more products launch next month at CES, such as these 42-72-inch models and 150-inch projectors which LG's been spouting off about, as so far it's only launched the 47-inch 47LH50 and 23-inch LCD monitor in Korea.

Sergio, my youngest brother, bumped against the piece of furniture that supported the TV. The heavy CRT fell onto us, in slow motion. I tried to hold it, but it was too heavy for a little kid like me. Fortunately for all of us, my uncle Antolín was there: He jumped from the sofa to hold it himself, struggling to put the cathodic beast back on top of the stand. One second later could have resulted in both my brother and I crushed under that monster.

Many other kids were not that lucky. Three hundred in the United States alone died from 1990 to 2007. According to Gary Smith—director of the Center for Injury Research and Policy at Nationwide Children's Hospital in Ohio, and co-author of a recent study on 100 emergency rooms nationwide, published in the Clinical Pediatrics journal—there were 14,700 furniture-related accidents. Of those, half were due to TVs:

Every day, in this country, about 40 young children are rushed to emergency departments with injuries after a heavy piece of furniture has fallen on them. This is not a small problem; it's a common problem, and it's increasing.

A study by the U.S. Consumer Product Safety Commission—spanning from 2000 to 2006—supported his paper: 42,700 injuries and 180 deaths related to appliances and furniture were registered, 87 of those directly related to televisions. Both the Clinical Pediatrics paper and the government study showed dramatic increases over the last few years: 18.8 per 100,000 people in 1990 vs 22.9 per 100,000 people in 2007.

The reason for that increase? Apparently, we have to blame flat TVs. They are not the actual killers, however: The real killers are the CRTs that the flat TVs are replacing. As parents buy new TVs, they move the old CRT giants into kids playrooms. Those are the ones falling, killing or injuring children.

So, if you have kids or know someone who is doing this, make sure that the TVs are fully secured against kids bumping against them. That, or have an superhero uncle available in the room at all times. [NYT]

I wouldn't want to string all that copper, but I sure don't mind looking at it. [Hack a Day via CruchGear]

Resolution aka 720p vs. 1080i vs. 1080p
Resolution is pretty simple—it's the number of individual dots (pixels) that make up a display, arranged in a grid. However, when it comes to TVs, we tend talk about it in a slightly weird way, as lines of resolution (think of a FourSquare board), and we tend to do it in shorthand. So, for instance, what's considered "standard definition" is a resolution of 640 x 480, which refers to 640 vertical lines, and 480 horizontal lines. A 720p TV has 720 horizontal lines of resolution, and most typically, 1280 vertical ones. A 1080i or 1080p TV is 1920 x 1080. And the whole 1080i vs. 1080p thing—i stands for interlaced, where only every other line of resolution is displayed, while p is for progressive scan, where the whole picture's displayed at once. Really, since even the cheapest sets are progressive now, you don't have to worry about it.

An important thing to consider, however, is the Lechner Distance, or the distance at which your eye can actually process all of the detail in a 1080i/p resolution image. While you should consult the chart, basically, if you're sitting further back than 7 feet from a 52-inch TV, your eyeballs can't actually resolve the difference between 720p and 1080p, so you might as well save the cash.

Motion Resolution
A somewhat trickier spec that some TV experts swear by, it refers to how well a set's resolution holds up when stuff's actually moving on the screen, like a baseball player running down a field. Plasmas tend to have better native motion resolution than LCD, but LCD has been fixing this problem. (See "hertz," below.)

Viewing Angle
Basically, it's how far to each side of the TV you can be and still see the picture, measured in an angle that is, naturally, less than 180º. Again, traditionally this was more of an LCD problem than a plasma one, but all TV technologies have had some issues in the past, and the worst offenders used to be DLP and other microdisplays.

To see viewing angle at work, start where the picture on a TV looks best, and move to one side—now note where the picture starts looking weird, with the colors changing, washing out and getting hard to see. Nicer sets reach nearly 180º, so plenty of people can take part in the HD glory.

Hertz, or What 120Hz and 240Hz Mean
Hertz is basically just the number of times the image onscreen refreshes a second. Because of broadcast standards, TVs in the US need to be 60Hz, meaning they refresh the image onscreen 60 times a second. (In Europe, the standard is 50Hz.) Video sources are generally 30 or 60 frames per second, because of this, and a regular video camera shoots at 60fps a second. So typically, 60Hz sets are the norm.

Lately, though you have 120Hz, and even 240Hz sets, all of them LCDs. They do this to increase motion resolution—see above. A 120Hz TV refreshes 120 times a second, and it comes up with those extra frames by making them up—either duping the frames that are there and putting black spaces in between, or by splicing in intermediary frames that are basically realtime morphs of the two frames they come between. Stuff looks really smooth—sometimes too smooth, true—but the point's to fight LCD's motion blur disadvantage against plasma.

240Hz is another ball of sticky still, promising less motion blur, but with a tradeoff. but there are two different ways to achieve it. One way's kind of cheating, in that it's a 120Hz that uses a flashing backlight to simulate 240 frames a second. The other, more "legit" 240Hz is genuinely faster, with images staying up on the screen for just 4ms before moving to the next. There's no real way to tell which kind of 240Hz a TV uses (though a "scanning backlight" is a tip off it's not the "real" 240Hz). There is a law of diminishing returns in reducing motion blur as you climb past 240Hz, but for some serious AV nerds, like Home Entertainment's Geoff Morrison, it does make LCD TVs more watchable.

Plasma TV brands sometimes boast "600Hz," but that's mostly to show off to LCD shoppers that these kinds of motion-blur refresh problems are really specific to LCD. It's not so much a spec as a declaration of the tech's superiority in this department.

To make things just a tad weirder for you, films have been shot since ancient times at 24 frames per second, so many TVs have a 24P mode, meaning the screen refreshes 24 frames per second, or in multiples thereof. (Any mathmagician can tell you that both 120 and 240 are divisible by 24.)

Plasma
The basic way plasmas work is that there's a party of noble gases trapped between two glass panels that are zapped and light up all pretty. More practically, what plasmas offer over LCDs is superior color (often), better motion (typically) and deeper blacks (always and forever, with a couple of exceptions). The tradeoff is that they're more power hungry, and generally heavier.

The life-or-death questions people have about plasmas are almost mythical now: Burn-in, where an image is permanently etched into the panel after being left up on screen too long isn't really problem anymore (unless you're sadistic to your TV). The "Denver problem," where high altitudes affect sets, is less of an issue, but it exists: If you live at 6,000 feet or higher, you should read this summary by our friend David Katzmaier at CNet. Panel half-life is a very long time, now, about the same as LCD's backlight (which, of course, could be replaced, but we're talking like 10 year out). When it comes to the cheapest TVs, 720p plasmas are hands-down the safest bet for best picture quality.

LCD
The people's HDTV technology, LCD, stands for liquid crystal display. The liquid crystal part is a gel that sits in front of a backlight, which is divided up into pixels. There are two main kinds of backlights used, CCFL (pictured, via Home Theater Mag) which are like the lights in your high school cafeteria), and LED, which we talk a bit more about below. There are two major kinds of LCD displays. There's the traditional twisted nematic kind (TNT), which is cheaper and known for faster response times, and then there's in-panel switching (IPS), which is more expensive and usually slower response times, buuut it's got a wider viewing angle and better colors.

On a broader level, the stuff to consider with LCD when it comes to actually buying a TV, is that, on the cheap side, LCDs tend to have worse motion and less excellent contrast ratios than plasma. You step up a bit, and it starts to even out. Especially if you pony up for the best of the best LCD TVs, typically lit up by LEDs. LCDs in general are way more eco-friendly, slimmer, and—because of their backlights—better to watch in environments where you're gonna have a ton of light spilling in.

DLP
DLP is a rear-projection technology made by Texas Instruments that creates the image onscreen using a whole bunch of tiny mirrors that reflect light through a lens. The big thing about DLP sets is that they're, um, big and for cheap—a 65-inch DLP set is just $1500. But you're probably not gonna be mounting this sucker either.

DLP is the last survivor of the "microdisplay" projection TVs, that also included LCD and LCOS techologies. They are great on contrast, but they got killed by flat panel because you can't make them an inch thick.

Laser TVs
Mitsubishi's LaserVue TV is a microdisplay projection set (with a DLP chip) that is lit up by lasers instead of just focused light. Thanks to this, it delivers some of the most amazing colors and deepest blacks possible, as good as plasma sets, but at a ridiculously low power consumption. Sadly, you'll probably never buy one, and not just because it's $5000 for a 65-inch set.

Contrast Ratio
So, technically, contrast ratio is just the ratio between the brightest and darkest images a display is capable of showing, which sounds like an objective enough specification. But like many specifications, this one has been turned into a marketing tool, and subverted to a point where it is not helpful. In the lab, there are several kinds of contrast ratios: Static, which is the ratio between the brightest and darkest a screen can display simultaneously, and dynamic, which is the darkest and lightest a screen can ever be at any given time. Sadly, it's this latter figure that most TV makers brazenly display on their boxes, to the tune of ridiculous numbers like 1,000,000:1 (or more). It's utterly meaningless, and you're better off ignoring it.

OLED
It's the beautiful future of television, but vastly too expensive for anyone but CEOs to own right now because OLED displays are really hard (read: expensive) to make at large sizes. "OLED" stands for organic light-emitting diode, and what's special is that the individual pixels light up by themselves, like plasma, but can be laid out on a single sheet of glass (or plastic), like LCD, so they get the best of both: They're super thin, they don't need a backlight, they have higher contrast, and they're energy efficient too. Also, they may one day—soon—be bendy!

LED TVs or LED Backlighting
While a standard LCD set is lit up by a cold-cathode fluorescent lamp (think dreary lighting from high school), the best LCD sets use LEDs (light-emitting diodes). They can be configured a few different ways: Edge-lit, where the LEDs are arranged in strips along the sides of the TV, and allow it to be super-thin; and backlit, where a grid array of hundreds of LEDs sits behind the screen and, with local dimming, where clusters of lights turn on and off individually, offers the best LCD money can buy. Three of the five best TVs you can buy are LED-lit, if that tells you anything. And no, they're not cheap.

3D
If you thought you heard a metric shitton about 3D this year, just wait for 2010. We have a giant primer on 3D tech right here, but there's just a couple you really need to know. Polarized 3D glasses are the cheap 3D for the masses—i.e., IMAX—where two synced projectors throw out two different images are slightly different polarizations that can only be seen by one eye at a time, making your brain see stuff in 3D without that annoying red/blue thing.

And while we kinda made fun of them, shutter glasses are actually the way 3D is moving in nicer implementations, from Panasonic and Nvidia, among others. Essentially, the glasses are battery powered, and shutters blink rapidly over each eye timed to the refresh rate of the display, so each eye sees a slightly different image as the shutter opens. It works better on plasma than LCD (even 120Hz models), in our experience.

Anti-Glare vs. Anti-Reflective
Anti-glare and anti-reflective displays, surprisingly are not the same thing. Anti-glare displays often try to diffuse light coming at a display with a treated or textured surface, almost like a "matte" finish. It's about cutting back external light hitting the display, but the tradeoff is that the picture coming through may not be as clear. Anti-reflective deals with light that comes from the display itself, as well as external light, and handles this with special coatings or films that minimize reflections from all angles to make the picture clearer. (Just think about eyeglasses, with that greenish coating. Same idea.)

HDMI
Honestly, the only thing you really need to know about but the High-Definition Multimedia Interface—you know, HDMI—is that the cables in most retail stores cost waaaaaay too much. If you pay anything over $10 for an HDMI cable, you are getting suckered. Order cheaper cables from Monoprice.com and other retailers—they do just fine as long as you're not installing them inside your walls. (If you're doing that, you should pick something heavily coated and insulated, and built to last a few generations of TV.) Oh, and there's a new version coming out—HDMI 1.4—that supports higher resolutions and internet. Not only will that require brand new HDMI cables, it will require new TVs and new content too, so it's a ways off.

The regulator is seeking comments "on how to encourage innovation," which basically means how to move past the total failure of the CableCARD system and on to something that will democratize how and where you can access cable video streams. If you're never heard about the CableCARD system, it's effectively the only thing keeping you from using your Xbox 360 as a DVR. A potential change could
open up cable signals to all devices, including your TiVo and Xbox 360.

And until very recently, you couldn't even get your Windows PC to be a DVR unless you bought it OEM from HP or Dell or someone, where they would install the CableCARD for you at the time of purchase. Quite opposite from the way people pictured CableCARDs would work—and how it will work shortly.

Just how bad is it? Ars Technica points out that in the FCC report, a grand total of fourteen non-leased set top boxes were available in the US at retail in 2008. That means that nearly every set-top box in the US is leased by a cable company, allowing them virtually unlimited pricing control and no incentive to innovate. Compare that to the 879 devices for sale in the truly competitive mobile industry, and you can see just how throttled the market is by the cable industry.

There's no telling what exactly is going to happen here, but at the very least it's good to see the FCC continuing their push for openness and sanity. We've waited long enough for something that's really not too much to ask. [ars technica]
