I have been following this thread for a while, and I just wanted to say that I have two DirecTivos, and R10 and an HDVR2, and they sometimes (If not all of the time), reboot at the same time! I was working in one room (with the HDVR2 in the same room) and I hear the fan kick up and the record and power lights flash. When I walked into the other room, the R10 was rebooting! They were on different channels, and neither was recording anything. By the way, is there any possibility of dish types having an effect on this? I don't think that every DirecTivo in the nation is having this issue (I think Directv would work a little harder on a fix if that were so). So if it helps, I have an Oval 3 dish.
