I just got some extra money so I'm gonna get a Sony DE845 receiver which can do Dolby Digital decoding. Now does that mean I can use the digital out on my MP3+ and get true Dolby Digital all the time? Or do I have to get a new Live 5.1 series board to make it work? The creative site really doesnt explain anything. And my drivers don't really have an option to turn on Dolby Digital anywhere. Anyone know how to setup a sound system like this?
