I just got a new 7.1 surround sound system by creative. I have it set for 5.1 because the dvd i want to watch only goes up to 5.1 The problem i am having is, it only plays through the front two and the middle. not the rear too. I have tried it in WMP10, PowerDVD, and InterActual Player. Also it does not work for simple mp3's as well. However, mp3's work in jetaudio. that is the only program that i have gotten mp3's to work in. I also tried and failed to get mp3's to work in itunes in 5.1. if anyone knows how i can fix this please post.
