My forth 522 dvr in less then one year just went today. I don't even use my dvr that much. In the past they were freezing up all the time. This time the receiver just kept resetting it's self. I even unplugged it and plugged it back in and it continued to reset it self every five minutes. When is dish network going to fix these 522's? I love Dish Network but i'm getting sick of paying all the shipping fees for the replacement DVR's. Has anyone else had this many problems with these things?
