Onset delay for playing audio on a slide

[David McFarlane]

John,

Um, yes.  Starting an audio file with some delay after starting a 
video equates to starting playback of the two files 
sequentially.  You are merely stymied by seeing your video stop when 
the sound file starts.  My guess is that you do not know about the 
Stop After property of MovieDisplay and SlideMovie objects.  This is 
set to Yes by default.  Try setting it to No and then do as I 
suggested earlier, and see how that works for you.  I cover all this 
in my online E-Prime course.
