Jim-
I had the same problem a few years back. I found a couple of solutions to work. The best solution is to use a good quality isolation transformer in from of your a/v system. I build my own using a Plitron 3000 watt medical grade transformer.
Next method is to track down all the culprits in the house. Place a bypass capacitor across the load at the location of the problem. This method worked good for me on certain situations (lighting).
Forget the suggestion of power conditioners. I tried everyone from API to Tice to PS Audio and everyone in between. The only thing that helped was the isolation transformer. A balanced (60/60) would also solve the problem. Bpt makes some very good units for the price.
Hope this helps...
