In the current release of QuickTime, MovieAudioExtraction only works
for audio data (ie. not MIDI data). (It is only supported by "Sound"
tracks.)
If you synthesize audio data from your MIDI data first (eg. convert
to AIFF), then yes, it will work. One way to do that is with
ConvertMovieToFile, which would be convenient for you, since you
already have a Movie. You then open that AIFF file the same way you
opened the MIDI file, and MovieAudioExtraction will work on _that_
Movie.

does it work for you? i think it's reasonable to expect it to
work. is it true I have to use some OLD API to convert it to an
AIFF first??
