Simply random stuff

Does that include Dolby Digital AC3 as used on DVD-Video? Because a lot of 5.1 soundtracks are DVD-Video with either AC3 or DTS tracks.

I do believe AC3 has a 5.1 side and a 5.1 rear option. The whole side/rear business seems to only apply to 5.1, as no other channel config offers that kind of option, except for 3.0 and 4.0, which can either be LCR and Quad (the normal modes) or Dolby Surround (where there is a single rear channel that's bandwidth limited per the original spec).
