This is what I have: -Zenith 27" TV -Time Warner cable, with Scientific Atlanta Cable box (has cable in/out, tv & vcr out and one aux in) -Phillips DVD Player -RCA RT2380BK 400 Watt Home Theater System. At the time I tried hooking the DVD player up to the receiver and the receiver up to the cable box, but that's not working. Any suggestions on how to get this to all work together? My cable box comes with one of those 5 device remotes (aux,dvd,audio,tv,cable). Will I have to disconnect the cable input from the back of my tv to get everything else to work. Also, before I got the cable, I had the home theater system hooked up and it only worked with the DVD player. When I was watching regular tv with an antenna, the home theater system wouldn't work. What was up with that? Thanks a lot and let me know if you need more info.
