Last night the picture started freezing and a black box would appear intermittently on the screen. This morning I got nothing so I reboot. After the welcome, powering up screen, I hear the unit shutting down and I get a message with a sun saying "The internal temperature was too high. The DVR has been shut down to avoid damage to the hardware". This unit is not hot at all. I have had it unplugged for many hours now and I still get the same message when powering up. Is this unit dead? Will I ever be able to access the programs on the list again (if no, my family will freak!) Anyway, just got off the phone with retention. Got the $19.95 shipping deal. HR20 should be here in 2 business days with a new dish install set for Tuesday. My family was dead set against losing TIVO, didn't care about the new HD channels, but now I had no choice. We need to watch football this Sunday. Any insight for this problem is greatly appreciated. Thanks.
