I was noticing how many Xbox Games are now encoded with Dolby Digital and thought how cool it was... Then I start thinking to myself, wait the xbox doesn't have any form of digital out so how would you get dolby digital? My answer was not hard to find.... you can buy a The Xbox Advanced AV Pack allows integration between the Xbox video game system and televisions or receivers that utilize optical digital audio input for Dolby Digital playback. I was wondering if anyone has there xbox hooked up using this method and if so, how is the quality of the dolby digital? Worth the 20 bucks for the chords? Thanks, Craig C.
