Well I have a crappy home theater in a box. It has a built in dvd/cd player and claims to do 5.1 audio. The manual is no help at all. It came with a center, 2 fronts, 2 rears an a sub. DVDs and Audio cds sound great. When I hook my games in to it using the AV wires I only get sound from the front right and left. It doesn't have a fiber input but it has a digital input. The only problem is the digital input is labeled Digital Audio OUT. Wtf is the point of digital audio out on a recieve? Is it really supposed to be labeled digital audio out? I got this as a gift from a friend thining I would be enjoying games in surround sound.. ::Cries:: help me!
