I have a TiVo premiere that's a few months old that I keep finding rebooting. It hasn't done it yet while I've been watching tv with it. Like last night I turned on the tv and it was stuck on the almost there screen. I had to unplug it and replug back in and then it would boot up normally. Came home at lunch today and noticed the green light was on as well and sure enough I turn on the tv and its at the almost there screen again. Just sat there until I cycled power. It's been doing this for about the past week. Any ideas on what might be causing this and how to troubelshoot? The same model in the living room runs fine.
