SatAV, I have to agree, I ran into a problem like that quite a few tears ago. Could almost make out a menu. Turned out to be a TV across the house in a bedroom. . Had to unplug it to get a clear picture in the living room. 60Ft between 'em, but fed with a common drop from splitter-amp. Fixed with an attenuator in line with the bedroom TV. (Not the best solution, but it worked.)
