I don't think it's even possible to do this in general because
inter-frame rates don't have to be a constant. The engine calls the
QuickTime function GetMovieNextInterestingTime() to determine when the
screen needs to be updated. If you know the frame rate and that it is
constant, the math to convert from a time to a frame is pretty trivial
(e.g.: currentTime / timeScale * <frame rate>)
