I've developed a CBT that uses a number of QuickTime movies that 
contain a Flash track for animation and a sound track for voice-over. 
I'm now being asked to add a text track for captions for those users 
who don't have sound or don't want to use sound (in a shared office 
for example).  QuickTime supports the addition of a text track, so I 
could have a single movie file containing all three tracks (video - 
Flash, sound - voice-over, text - captions).  Is there any way I can 
enable/disable QuickTime tracks in a movie under control of my 
MetaCard stack?  QuickTime Player supports this, so it's clearly a 
feature within QuickTime movies, it's just than I can't see how to 
get at this control from within MetaCard.
