FINALLY. Microsoft and CableLabs are finally opened the door to have regular people add in CableCARD tuners by themselves, after they've purchased the PC and set it up. This is good news.
What it means to you, theoretically, is that you should be able to go out and buy CableCARD tuners and add them to your Windows 7 machines to turn any old machine you have lying around into an HTPC. Also, they've raised the limit to four tuners per "tuner type", so you can have four digital cable channels simultaneously without any kind of special setup.
There is also a new Firmware update for ATI TV Wonder Digital Cable Tuners to mark copy-freely content—the content you can move around your network and portable devices. [Microsoft]
