I need to connect my computer to my 42" plasma television through an LG combination dvd receiver that is connected to the TV. The receiver has an orange coax in, optical in, s video out, and a set of component outs. The TV has an audio pc in, and 15 pin pc input, an optical and digital audio out. My computer has digital audio in and out, a set of component in and s-video, and a tv (cable style) in and out. What sort of connector do I need to buy?
