Ours freezes too!
We recently 'upgraded' to a 522 6 weeks ago and have had nothing but problems with it. The picture was freezing constantly. We've had 5---yes, 5 new receiver boxes so far. The freezing still comes and goes, although not as often, but our biggest problem is our local channels stretch across the screen after 6:00 p.m. at night. Did you happen to have this issue??
