Okay, I've got an LG LCD TV, a Sony DVD player, and I just bought a Kenwood Surround sound kit. I can get the surround sound with the optical cable going to either my 360 or my DVD player, but how do I get it for my regular TV and the XBOX that is connected to that TV? Do I have to use component cables? I tried using a set of those old red and white plugs, but no luck. cheers.
