Is anyone having trouble with the built in OTA HD tuners in a 622 or 211 receiver? Many people in the Milwaukee, WI area and Madison, WI area seem to be having problems. In Milwaukee it is ABC 12-1 and in the Madision area it is 3-1. It seems to have started about 2 mo. ago after a software upgrade from Dish. Many channels suddenly jumped from a 85 or 90 signal strength to 100%. after that the local ABC channel (showing 100% signal) pixelates, drops sound or just goes from 100% to 0% for about a second and then cames back at 100%. this happens anywhere from every 30 sec to 1 min. It makes it very hard to watch TV that way. The people in Madision, WI are having the same problem with 3-1 (don't know what network that is there).
