The TiVo HD launches, and with all the expected features and highlights. Users can expect:

Record 20 hours in HD (or up to 180 hours in SD)

HDMI / component out up to 1080i

Dual frontal CableCARD slots (plus M-Card compatibility! slots are behind the gray plastic bar), single ATSC tuner, analog NTSC, etc. (Same deal as Series3 though, only two tuners can record at the same time.)

No frontal display, Glo remote, or THX cert, still no support for multi-room viewing, TiVoToGo, and TiVoToComeBack
