I have a 6 month old Tivo Premier and I have an intermittent problem - When I first turn on the TV, I can't rewind. It's like the Tivo went to sleep, and when I turn on the TV it wakes up. But it's not just when the TV has been off for a long time. Just this afternoon we were watching the Olympic trials. We stepped out of the house for a bit, so we hit record, then turned off the TV. When we got back and turned on the TV 20 minutes later, we couldn't rewind, and the missing time wasn't recorded either! The "recording info" said 40 minutes, but there was only 18 minutes recorded and we could see the splice from the point where we turned off the TV to when we turned it back on later. WTH? We've had a number of other problems with Tivo randomly just not recording the shows it's programmed to get, and the only time it happens is when the TV is off. Really frustrating, when that's the only reason we have it! Does anyone have any ideas?
