Hello.. I have a 522 and love it. Question is. I had about 30 hours of shows recorded on the dvr and I was done watching one of them and stopped it and then deleted it. All was normal. I went back a few hours later to watch something else and then dvd list was blank. The amount of time left on the dvr was there and it was about right with what I had recorded. Can I get the programs back? I cant see them. Called Dish. They had me reboot the 522 and still nothing? Any ideas?
