It's not the production of surround sound. Whatever that entails, it's relatively straightforward. It's the multiple forms and distribution mechanisms of surround sound.
In a typical home surround setup, the surround speakers are behind the listener. In a typical theater surround setup, the surround speakers are behind, to the sides of, and in front of the listener. Where surround in the first situation can "enrich" the sound, the same type of surround applied to the second can make speech unintelligible to those in the rear of an auditorium for whom most of the surround speakers are in front of them. So we're doing different surrounds for homes and theaters.
Then we've got some distribution requiring AC-3, others Dolby E, others six-channel discrete, and, for yet others, LT/RT intended for ProLogic2 decoding. Our live motion-compensating HD standards conversion, and, yesterday, for some distribution, compensating with a one-hour delay for some European sites that needed compensation for the earlier onset of Summer Time in the U.S. than in Europe (some 29.97 and some 25) just adds to the fun.
As for the non-CRT distribution, we are dealing with theaters that are using digital-cinema projectors (probably all DLP) and with theaters that are using transmissive-LCD so-called "e-cinema" projectors, with HD distribution to homes, and with SD distribution to homes. You've no doubt seen the thread here about the low-key-light complaints regarding LCD viewing. We've discovered such issues as the fact that some theaters that have been showing the cinemacasts on projectors normally intended for viewing the ads played when the lights are up may have been boosting the brightness to the lights-up condition and then trying to compensate for the reduced contrast in the lights-down condition by cranking up the contrast knob.
We can have a lighting director, opera director, and TV director all ooh-ing and ahh-ing over a gorgeous effect they've achieved on a CRT monitor, and we can point out on our own LCD and plasma monitors in the control room how that will not make it to homes with those display technologies, and it's like popping a child's balloon.
