Advertisements Must be doing something wrong. I got my TivoHD setup with the cable cards. Called Comcast and activated the cards. I seem to get the digital channels on the TivoHD but only the basic channels, but when I go upstairs my old TV gets all the higher level analog channels such as CNBC. What gives? Why can't I get these higher levle channles on my brand new TivoHD that my 10 year old analog TV has no trouble getting? PS I have read quite a few posts, but I get confused on what exactly is digital and what is analog. Hey, at this point I'll take the channels any way I can get them as long as I get the channels.
