Ok, I feel like a complete moron for having to ask this, I do know a fair amount about audio/video, but most of that is audio. Ok so, i just got a sick new surround from my grandpa. Got it all hooked up and all, but, my tv does on have outputs. I'm running straight coax to the tv. Do they make anything that I can turn my coax into RCA and run to my receiver?? Thanks for your help guys!
