I have a Series 3 HD TiVo. I use it to record OTA HD (among other things). Up until a couple months ago, this has been working fine. The first sign of trouble was some of the CBS HD recordings had no content. When I went to Live TV and selected the channel (13-1 in the TiVo Guide), there was no signal. After lots of messing around with the antenna and connections, I tried the Channel Scan, which found CBS on channel 32-3 and indicated it was already in the channel list. At that point, tuning to 13-1 from the Guide worked fine and recordings worked fine.
Last week the same symptoms reappeared. This time, when I go through the Channel Scan, it finds 32-3, but indicates that it's NOT already in the channel list. I can add it to the channel list, but the Guide will list all the CBS shows on 13-1, where there is no signal and it will not list any shows on 32-3 (it says "To Be Announced") where the actual signal is. Throughout all of this, the HD tuner in my TV was always able to receive CBS on 32-3, so I have no reason to think the local broadcast has changed. Other OTA HD signals (NBC, ABC, FOX, PBS, etc.) have had no problems. One other curious thing: if I use the TiVo's signal strength meter on 13-1, it shows no picture (screen is all gray) but indicates it has acquired a digital signal and reports a signal strength of about 80. 32-3 behaves similarly, except there is a picture there.
It seems that a couple months ago, I was able to convince the TiVo that 32-3 and 13-1 are the same, but it's not working that way any more, and I'm out of ideas ... any suggestions are greatly appreciated.
