[jitter] [bugreport] inserting audio track in jit.qt.movie

This appears to be a QuickTime bug wrt timescale and audio tracks.  
There's an ugly workaround, which is to set the timescale of the  
tracks to match that of the source tracks.

The best thing to do would be to use the magic track number -1 for the  
first insert operation on each track to create a new track with  
identical properties as the source data. Then you can avoid the whole  
problem.

I've modified your patch to hard-code the necessary timescales for the  
movies you sent to support. Jitter for Max 5 will support creating new  
tracks with the track's timescale (which can be different from the  
movie timescale) as an optional argument.
