Hi, Hope you can help. I've used all my component inputs on the Denon 3805 (TV/DVD/Xbox etc). I wanted to set up my Gamecube to the amp also. So thought I'd just by a S-Video cable plug it into VCR1 (for example) and away we go. (Also wanted to see how it looks via upconvert to component?) But all I'm getting is sound? I've messed with the settings but don't know why I can get a picture? Am I missing something here? thanks.
