I've been through several 612 boxes but they all reboot on their own. Some more than others. The first one was the worst and oddest. It would reboot watching the playback of SNL opening skit. Did it everytime. I'd have to ffwd past the point. They tell me there is no hardware or software issue with the 612 so I guess they want me to accept I'm just unlucky. It's not overheating unless room temperature is too hot. Anyone else have this issue? Better yet a solution? Right now I'm just planning to coast then switch providers next year.
