Hi, I just activated Comcast with Tivo HD Series 3, and went through the regular Tivo setup, i.e. selected Comcast as the provider, it showed me one channel (Food network) and asked if it was correct, and I said Yes. Then it went ahead and downloaded info from Tivo. I can receive channels fine (including HD channels), but channel lineup is messed up for some HD channels. For example, 709 in Guide (channel list when you hit guide) is shown as KQHD and it is correct. But, 722 is shown as HDT (Discovery HD) in Guide, but when you select it, you see ESPN2 HD. 730 is shown as HBOHDP, but it actually is Discovery HD. Am I doing something wrong here? Any idea how I can fix this? Thanks a lot for your help.
