Ok, here's the deal, I have a digital cable box, a dvd/vcr combo player, and an xbox. I need to hook all of these up to the tv. First I just tryed using the rf mod i been using to watch dvd's on my xbox so i wouldn't get the fade effect and it worked, but now that i have a dvd player i don't need it anymore. the rf modulator worked, but when i try using the av cables that came with the xbox to hook it up i can't figure out what to do and where to start. If you could help me out I'd appreciate it greatly.
