I had the exact same problem. I had schedule shows on 5.1 to be recorded through my TiVo and when I checked the TiVo said it here wasnt a signal on the 5.1 channel. I decided to check a connection direct to my digital TV the TV could no longer receive local channel 5.1
I did a rescan on my TiVo HD and it added some new channels and duplicated a few like 7.1, 7.2. 7.3 Then I deleted the OLD TiVo Channel 7.1, 7.2, 7.3 and selected the new I was able to see all the 7.x channels again. However I found I still could not get 5.1 or 2.1 but could get 202.1 (fox) 205.1 (cbs)
I also did a rescan on my HDTV; I was able to see all the 7.x channels again. It still could not get 5.1 but got 205.1 for CBS, and 202.1 (fox) I guess you just have to hunt through the QAM channels till you find what you want.
I think COMCAST is pretty bad making this sort of change to paid subscribers without publishing the new QAM Lineup channels. There is a law that requires cable companies to include Local HD TV Channels as unencrypted channels or also known as QAM Channels I guess switching these channels without notice is COMCAST way of playing with their Basic Cable subscribers if they keep that up, maybe the can make the number 1 most hated company I believe they are already in the top 5
There is not law like that. COmcast does not have to give you HD Local channels in clear QAM,
