The finally gave up and sent me a new unit which had the same problem! After further research, I realized that my UPS did NOT have Automatic Voltage Regulation. AVR keeps the voltage at an exact level... a UPS does nothing unless the power drops to below a certain threshold (70V, etc.). I got a unit with AVR and all my problems went away. The Dish techs never thought to mention this so I am passing the info along!
Bottom Line: It is very likely that you will need to purchase/use a automatic voltage regulation unit with the Dish DVR units (they are known to have flaky PSUs). You can get AVR in a UPS (and thus have battery backup) or just AVR capability in a surge protector.
Well, I have the Canadian version of this box (called the 9200, through Bell Expressvu) and I'm on unit number 3. First box was bought in August 2005 and worked flawlessly (except from odd bright green/yellow stripes once or twice) until January 2006, when all of a sudden, "you have a serious hard drive problem" appeared on screen. A few minutes with tech support and they determined a new unit should be sent to me. A few days later, it arrived.
After hooking it up, it was clear that the replacement unit had a problem of a different sort, but only on recorded programming. Every 20 seconds or so, the playback (video and audio) simply freezes, just like pressing the PAUSE button for a moment. After verifiying that this issue affected only material recorded onto the HD (LIVE stuff seems fine), I contacted tech support again and we went through all the hoops....still could not rectify this issue. So he said they are sending me yet another unit. He says they have received "some other callers" with this problem.
When it works, this system works well indeed. But the hard drive and the software/hardware buffers that allow the input/output of programming from/to multiple sources/displays seems to be under-designed for the tasks it is being asked to do.
Yes, I have the unit hooked up to a Belkin UPS with voltage regulation.
We'll see what happens with the third unit.
