It occurs to me that you might need to go through guided setup again to straighten out that double channel thing, and I can't think of what accidental key presses could have caused it, so you can let him out of the doghouse.Two issues, may be connected.
1. I have a Series2 that no longer recognizes my digital cable box. I am ok on the channels <100, but the channels that need to go through the box aren't changing(Tivo changes, not the box), have to use cable remote.
2. All of the channels on the Tivo guide now are doubled. I have checked the list in settings and it is correct(only 1 check mark per channel).
Any ideas? FYI-My husband said he rolled over on the remote, could he have pushed a button accidently that is causing the double listings?
These issues did not start at the same time.
Thanks for any help
Before you do anything else, drill down through the menus until you get to "Restart the TiVo DVR" and do that, and after you press the thumbs down 3 times and are about to press "enter", be ready to unplug the power cord from the wall socket/UPS as soon as you do press enter and the screen goes blank.
Let it sit for a few minutes, then plug it back in.
If you've still got the problem, then you can go through GS again. You'll need for the cable box to be feeding a video signal into the TiVo when you do.
