I am working in Movie Maker for the first time and I am adding in little bursts of sound (Chewbacca noises actually) in some spots.  If I do them all in order and make no changes it is fine.  But I have to go back and add or delete one in the middle of the movie ... they all move. It is like they are somehow connected in a continuum and making an edit in the middle lengthens or shortens the continuum which changes the position of each audio segment.  Please help, I am in a crunch to get this done tonight for a very large school event tomorrow evening.
