Not sure if this is in the right forum, but hopefully someone can help...Mods, feel free to move this if necessary. I have an older TV hooked up to a theater-in-a-box (college budget). The TV has no RCA in/outputs, so it's hooked up through an RF adapter right now. I'd like to be able to have cable TV and my PS2 play through the surround speakers. Is there any way to do this w/o buying a new TV? Thanks!
