I just purchased an Xbox and hooked it up to my HDTV and Dolby Digital receiver. When watching movies with Dolby Digital the center channel is used for dialog etc and I was expecting the same on Xbox games. However it appears this is not the case(at least in some games). I'm wondering if my Xbox is functioning normally and if others have noticed the same thing playing Oddworld etc. It would seem to me if a main character is speaking, the dialog should come from the center channel unless the positional audio capability is being used(for instance a character walking around a room). Of course it's up to a developer to decide that. Just hoping to get a few comments from Xbox gamers as to their experience with Dolby Digital and the use of the center channel in the games they have played. Thanks in advance for any comments!
