Audio Channels

This is the second cut with addition of 7.1ds in May 2010. This is not a standard, but a starting point for a discussion of how it might be done. Comments and suggestions are appreciated. How should it be routed?

Toy Story 3 is being distributed with two audio packages - one with a traditional 5.1 track and a second with the 7.1ds (discrete surround) track. The 7.1ds is a 16 channel version with the new channels on 11/12 with HIVI (if present) on both 7/8 and 15/16. (May 2010)
