Greg, The AA rating requires the AD to be its own synchronized track, not included in the integrated (main) soundtrack, which a very few specialized video players allow a blind user to turn on much as a deaf user would turn on closed captions. The AAA rating requires a separate extended AD, with the understanding that any AAA accommodation also meets AA (and of course A).
