Here's the much simplified version:

Boolean HasEnabledQuartzComposerTracks(Movie movie)
{
    Track          track;

    track = GetMovieIndTrackType(movie, 1, 'qtz ',
            movieTrackMediaType | movieTrackEnabledOnly);

    return (track != NULL ? true : false);
}

((**description).cType == 'qtz ')

yes, sample descriptions are native-endian in memory, or more precisely, the C fields of sample descriptions are native-endian and sample description extensions are big-endian.
