I just went to play an old DVR recording and discovered that ~300GB of recordings are just *gone*. Why would my DVR delete that much without asking me???
Given that I live alone and no one else has been in my apartment in a couple of weeks, I'm leaning towards some kind of bug or something. I'm really bummed because I had a ton of really awesome movies recorded.
Sadly this happened to me yesterday also. I contacted Dish and they are sending a replacement. For now on I think I will watch the shows I really care about faster and transfer them to EHD if I can't.
There's no known issues with the 922 deleting things on it's own, especially 300GB worth (we normally see all gone, or none gone). If it's the first time it happened, sorry, but I'd ask for you to wait (backup some stuff too). If it happened again, then I would replace the receiver.
Oh, and hard reset as always
For the people who had this problem, if you send me account info (including software version on receiver), I'll report the problems so that any trends can appear
