A question for everyone. I have a Sherwood 7106 that I want to run video switching through. I tried composite, but it caused a 3" distorted bar across the top of the screen. This stopped when I bypassed the receiver on video. The guy at Radio Shack called it 60 hertz interference. Has anyone ever heard of this? If so, any advise? I also have s-video inputs, and have thought of using these with RCA-S Video adapters, but would rather not go that route if possible. Any suggestions would be appreciated.
