I have a DTVPal DVR that was made by Dish Network. They stopped producing and servicing this unit.
The problem I have is that the picture will intermittently distort like it's receiving a weak signal. After so many of these the unit will lockup, and need to be reset. The signal strength is good, and I don't see anything obvious on the mainboard or power supply board.
I tried heating the boards to see if the problem would get worse, but it didn't. I tried disconnecting the antenna to see if it would do it when just watching a recorded movie, it still does it.
I've not checked...
