No, the movie itself is masked, so that in the Apple QT player it has a transparent background. For example, imagine it's a movie of a spinning ball. The window in which it plays in the RR player object is rectangular but the desired appearance is disk-shaped, with any objects behind the movie only obscured by the disk itself, not the 'empty' parts of the rectangle. This can be accomplished, but only if the object runs unbuffered, don't know why. Of course with an image (rather than a movie) based on a transparent GIF, there's no problem.

Yes, I think this is feasible, but I will wait until my publisher complains about the simpler solution before coding this more complex one! Thanks for the thought though.
