I have been using my av receiver to handle my video switching. Before I set up the Denon 1083, I was using my old Yamaha. I was starting to have some problems with the picture breaking up with the Yammie, and now it's doing the same thing with the Denon. I disconnected the s-video cable from the receiver and ran it straight to the TV from the satellite receiver, and presto-chango the problem is fixed, but now I don't have any means of handling the switching. Does anyone know what might be causing this?
