Why is my flash movie 'juddering' on a simple zoom?

Question

I've created a small flash movie which is basically a 7 second zoom on a photo. When I export the final movie though it's not a smooth effect at all - the only way I can describe it is 'juddering'. I've tried this movie on 15 pfs and 30fps and the effect is still the same. What am I doing wrong? How do I achieve a smooth zoom?

Are you creating a motion tween?  If not, here's a tutorial.
