Enough is enough. After having ALL the reported bugs with my 921, specially the zero recording and the locked aspect ratio and not trusting Dish anymore to fix the problems, my 921 will be returned to Costco. Time to test their return policy since I have the receiver for more than 6 months. What a piece of junk! Today it started "acting up" tuning to different channels than the ones I had selected and producing a black screen from time to time.
