I have some composite monster cables (red, yellow, blue cable-it just says sv1 video, and sheilded audio) they are pretty good, is there any reason i can't use them to hook them up my dvd to my tv in place of a composite cable? They have the correct connectors, so I plugged them in to the y,pb,pr from the DVD to the TV, I really couldn't see a difference in picture quality? Would I be hurting my equipment with this choice?? I just hate to spend 25$ on a new cable if i don't need it.
