TiVo's not the only box offering HD content from Amazon VOD, Roku has also announced HD Amazon downloads which are available today.
We knew TiVo was beta testing Amazon HD VOD,so it's not a huge surprise it's actually official today. TV shows and Movies will be available in HD with most videos supporting 5.1 surround sound.
Everybody is launching networked TVs it seems, but Vizio's "Connected HDTV" sounds killer: Built-in 802.11n Wi-Fi, with every service you'd want: Amazon, Blockbuster and Netflix VOD, Pandora, Flickr, Rhapsody, plus any other Yahoo widget.
Roku's Netflix box is currently a one-trick pony, but it's getting Amazon's Video on Demand later this year, meaning you can soon buy or rent and instantly stream movies and TV shows from Amazon's service.
