What we have now on DVD essentially exceeds that in theaters (for Dolby atleast) if you have a good enough system. With many people talking about 24 bit 7 channel audio as a requirement for HD-DVD, I got thinking... At what point does the audio format surpass the source audio. I mean only movies in the last decade or so even recorded the source audio in 24 bits, right? Hell, Star Wars didn't switch to 24 bit until Episode II. I mean, when do we reach the point where the audio is limited by the source for every release?
