I want to hook up this old home theater system that I got at a yard sale to my hdtv. The home theater system works fine. I just don't know what cord(s) to buy and how to hook it up. I also have an xbox 360 connected using red, yellow and white cables and I want to be able to use the home theater system while playing it. My tv is a Sylvania lc320lsx and the home theater system us a regent ht-391. The home theater system has red and yellow inputs for dvd, aux, and game/camera. There is also two yellow outputs for video and a t-a 1.6/250v fuse thing. Please help.
