I've had this DVR for at least 7-8 years. Over the past month when playing a recorded program, the picture will freeze & also go blocky looking, then it may return to normal or just sit there like it's "paused". I've discovered that if you push the 15sec rewind/replay button, the DVR may play OK for 1-10 min with no problem, and it will play the part OK where it had just froze up. So it's basically no problem with signal reaching the DVR, but something in the processor chip/board. It's not the HDD because when you rewind back from the spot in the program where it froze, it will then play OK after a couple of attempts.
So I rebooted the DVR last night thinking that may cure the problem, but it didn't. The DVR plays OK for about 30-45min, then goes into it's picture tiling/blocking & the freeze up. I then noticed tonight that when it's recording and your watching a recorded program at the same time, the fan on the left rear side of the DVR is not running. So I'll guess the DVR is getting to hot, which is causing the problem. And I'll assume the fan should be running all the time the DVR is on.
Anybody else ever had this Problem?
