I have an older 27 inch Panasonic. The best connection it has is a single s-video input. I have it hooked up to a hub, so I can run both my Panasonic RV31 DVD player, and my Xbox, in s-video, by switching back and forth between the two. My question: would there be a visual improvement, if I replaced the cheap Radio Shack s-video cables I use now, with something "better?" Remember, I don't have HDTV, so that is not a factor. All opinions are welcome.
