You should have a Dolby Surround setting on your reciever that you can set so you get sound out of the rear speakers. Also your reciever should have at least one if not more digital inputs on the back, they should be orange RCA type plugs (could have optical to). You can use a mono mini plug that goes to an RCA plug on the other end. Plug the mini into the Audigy, the other into the orange plug on the reiciever. In the Audigy menu set this plug for digital output, on the reciever, set DVD, Aux. or whatever uses the orange plug (some recievers are programable). You should be able to listen to DVDs from your computer on the reciever in 5.1 sound.
