I've bought TivoHD recently to replace my TivoS2 because I wanted to be able to watch HD channels that I'm receiving from Comcast as part of the basic package (ABC, CBS, KQED, etc). They're listed as channel 2.1, 5.1, 7.1, 9.1, 33.1, etc. The problem is that TiVo does not have any listing info for these channels, and only for their SD equivalents. I've read people saying that I have to get CableCard from Comcast to get TiVo to show programming info. That sucks! Why can't TiVo provide a way of marking specific channels as HD equivalents for some other channel? I don't want to buy a CableCard and have to pay extra to Comcast just to see the programming info (as I said I'm already receiving these channels). Another alternative would be to go with HD over the air antenna. Any suggestions?
