My memory was that the surround channel was added to one channel normally and to the other channel inverted, but the Wikipedia article on Dolby surround says it's phase-shifted 90 degrees in one and -90 in the other (and, apparently, multiplied by sqrt(2)/2). That's why I didn't mention specifics in my first post. But if you wrote a Csound orchestra to decode DTS noise into stereo, you certainly should be able to do it for plain old Dolby surround! Start messing with phase and adding channels together, and you ought to get something useful out of it.
