I attempted to add a 2nd TV to my Dish system, in which "TV 1" is a projector home theater system, and failed.  The setting to watch a satellite station was DBS.  Somehow this attempt corrupted my system's home theater receiver so now, if I attempt to watch a satellite station, I get video on one setting (DBS) and audio on another (VCR).  Neither customer service at Dish or the receiver manufacturer could solve the problem.  I'd appreciate any advice.  Thanks.
