Has anybody else had this happen? Does it indicate a problem? Yesterday, while I was watching tv in my living room, I went to click back into the recorded show I was watching before and suddenly all the colored lights on the front of the Tivo blinked on and then off, then it restarted itself. That went without incident and, fortunately, I was not recording at the time so nothing was interrupted except the 30 minute buffer on both tuners. It did change the channel on one tuner so that both tuners were on the same channel when I was back up. That seemed kind of odd. My Premieres are only about 3 months old. The living room one (same one) was having problems getting stuck at first (to the extent that I would have to restart it, or sometimes it ended up restarting itself) but nothing major and it seemed to work itself out and hasn't happened since the beginning.
