Xander,
I think the problem you are observing is not the problem I'm talking about.
On my computer (500 mhz) Media Player shows about 29.88 FPS, the same as for
several other MPG's I have made on the same programs. None of them have the
double image problem.  I spent several hours experimenting with different
frame rates, compression rates, bitrates, resolution, etc., and although
they made a difference in picture quality and motion quality, nothing
eliminated the double image. If you stop the video at any point, the image
is not double, so it seems to have something to do with motion. The only
thing about this one animation that is different from the others I mentioned
is that the ball is traveling in a circular path rather than in straight
line segments. Got any more suggestions?
