I currently have a Motorola 922 digital receiver, and subscribe to most of the digital channels on the G3 satellite. But, recently, I am having problems receiving a quality signal on 580, 581, 600, and 622. I can receive A&E, AMC, Hallmark, Lifetime, TVLand, CNBC, and MSNBC. I have tried tweeking the dish, the H and the V to no avail. I guess I am not sure what is going on at this time. Any ideas as to what the problem might be? I appreciate any ideas.
