I think something was posted about this a few months ago. Wonder if anyone else has this problem. I have two 622s. Not everyday but often enough to be annoying at 5:12 AM Central Time anything recording on Tuner 2 will be stopped and the channel switched to channel 101. Yesterday I had both tuners recording and was watching a previously recorded program. Both tuners stopped recording and I had only a blank black screen when viewed live with not even the info banner functioning. It came back after a few minutes. Even if nothing is recording I may find the receiver has switched to channal 101 on tuner 2. I'm guessing DISH is doing something at that minute to cause this. I haven't verified that it happens on both receivers on the same day but I don't think it does. One receiver is setup to get it's daily update at 3 AM. The other gets updated at noon so it doesn't seem to be related to the daily update. Also it doesn't seem to be related to those recordings DISH sometimes forces on us. Others having this problem? Any idea?
