Advertisements I have cable but no cable card or cable box. My local cable company provides the local networks in HD on their regular channels (channel 3 is 3.1, etc.). On my HD Tivo I have both the cable and an OTA antenna connected. I use the OTA antenna to record the local networks because Tivo will not display guide information for those channels on the cable. For instance, I have 3.1 for Antenna and 3.1 for cable, but in the guide information is only provided for the 3.1 off the antenna. I'd like to get rid of the antenna if possible because I get occasional interference, but I can't seem to figure out how to get the guide data to map to the digital cable channel. If I had a cable box the channels would be mapped differently (in the 500 range I believe)... so I think that might have something to do with the problem. Thoughts?
