Actually, I'm not quite sure if the problem is specifically with my receiver. I have a Sony STR-DE675 receiver, a Panasonic DVD-RV30 DVD player, a Fisher FVH-4903 VCR and a RCA 20" TV which is about 12 years old. I only use composite video cables and my TV only has composite inputs. Whenever I view source material that contains bright flashes of light or flashy edits the picture rolls vertically for a split second which I determined by reading the forums to be a vertical sync error. It happens with the DVD player as well as the VCR (video playback or tuner) which are routed through the receiver to the TV. I don't have the vertical sync problem when I hook a component up directly to the TV, so I think it just might be a compatibility issue. Before I got the Sony STR-DE675 I had a 20 year old audio receiver so I was using an audio/video selector (non-amplified) by Radio Shack and I had the same problem. It might be worth mentioning that I use both regular and gold plated composite cables. I think I either have to replace my receiver or TV. Since my receiver is under warranty maybe I can have it repaired. Please, can anyone give me some advice?
