DVR box began locking up.
I started having issues with my DVR box in that it would lock up while trying to pause, ff or rewind. Then it would not exit, or respond in any way. Powering down and restarting results in an error screen. Repeated attempts were fruitless. Shut it off for several hours then it works. For a while that is. After viewing for an hour or so it happens again. What can it be?
