I'm hooking up my current system (PS2) and others to my switch box on my new hdtv (I know, older stuff won't look good, etc). So far nothing except the PS2 works. I have a composite to the switch box, and going from there (comp for PS2, standard av or s-video for n64, etc). Do I have it reversed where I should go rca av to the switch box then comp, etc out of the box?
