I was wondering if anyone else had this problem. Last week a warning note came on the screen saying "remote batteries low" so, I changed them. Much to my chagrin my remote stoped working with the receiver. It would not respond to any commands. I contacted Dish and talked with one of their techs, going through various ideas, hard reboot, trying to change remote address, etc. The remote simply would not work. I've encounter several of the problems describes in this forum, stuck aspect ration, missing guide info, OTA channels disappearing, etc., but had never seen this before. Can't wait until April to get rid of the 921.
