Long time reader, first time poster... now on to the question (if this is the wrong forum for this please move) I've recently done some upgrading to my home theater setup. I previously had an old prologic receiver but just bought an Onkyo SR600. So far I'm happy with it, but I'm having one problem. When watching a DVD, I have a horizontal line that scrolls down the screen continuously. Here are the connections: DVD Player(Pioneer DV-C503) Video - S-video cable direct to TV (older Hitachi 27") Audio - Digital Coax to SR-600 Digital Cable A/V Composite cables to Video 2 on SR600 VCR A/V Composite cables to Video 1 in/out on SR600 XBOX A/V Composite cables to Video 3 on SR600 Composite Video from SR600 Monitor Out to TV With this setup the horizontal line moves down the screen during DVD playback. If I unplug the video composite cable from the back of the TV the line goes away and the picture is fine. What I don't understand is that I had pretty much the same setup on my old receiver (except cable signal wasn't running through receiver). I had both a composite cable and S-Video cable going into the back of the TV with no picture problems while watching DVDs. What would be causing this? Receiver? Cable? DVD Player? Any help is appreciated.
