Before I get targeted, I *did* do a dearch for Dolby Digital EX and the results were 152 pages of different threads, the vast majority of which dealt with movies,not hardware. Needless to say, ah weren't gonna be a-lookin' through all uh those threads! What is Dolby Digital EX and how does it differ from "standard" Dolby Digital? Is this sort of like THX and non-THX where the only difference (supposedly) is sound quality but there are no technical differences? Everyone seems to be psyched about LOTR coming out in DD EX. So, what in blazes is it?
