My Tivo HD keeps freezing (image freezes on screen) and then rebooting. I can watch it for about five minutes after it reboots and then the cycle starts again. To make a long story short, I'm curious as to whether a lack of sufficient power to the Tivo could cause it to restart. It's getting power, but I'm wondering if a new receiver could be causing the Tivo to not get enough power, which might lead to the reboots. Here is the longer version of the story: I've read the old thread on this: http://www.tivocommunity.com/tivo-vb/showthread.php?t=393114 I think my problem may be different, though - in that thread the problems seem to be related to either a 2008 software update and/or bad hard drives - and was hoping for some feedback from people who know more about this stuff than I do. I got a new receiver a few days ago. The problem never occurred before that, so that makes me think the receiver has something to do with it. The hard drive could certainly have gone bad, but that's quite a coincidence. I have an old APC UPS in my home entertainment center where the battery died and some of the outlets don't work. I plugged a power strip into one of the working outlets and plugged my stuff into the power strip. This was a few years ago, and I've never had any problems. I'm wondering, though, whether maybe my new Onkyo receiver could be drawing more juice than my old JVC receiver which could be causing the Tivo to get insufficient power and would cause the restarts. Before I spend $200 or whatever on a new UPS, I thought I'd check to see if I'm onto something or if the problem has to be something else (like the hard drive).
