I have had a 721 box since August, and it has worked flawlessly. Now, since a sofware upgrade 3 weeks ago, I cannot watch tv while the dvr records. Within 3 minutes of the time the box starts recording, I get a black screen. I shut off the box, let it sit for 10-15 seconds, then I get the picture back--for another 3 minutes, then it starts over again. At first, I would get the channel 77 "unknown record" error. Now, I just get the black screen.
I have called the tech support at dishnetwork several times, and they have not been helpful or even remotely sympathetic.
Any thoughts?
