Controling external movies

Is it possable to load an external swf file, that is a rotating movie into another file and still control it??

example:

I have a rotating object which I want to pause and play. I have loaded the rotating object into a window using the loadMovie command. I now want to be able to use the play and stop buttons to control the rotation.

Because the movie has been loaded into the window from a different location it does not have a path to target the play and the stop command to.

I also tried adding the play and stop buttons on the rotating object movie swf file. They load and are pressable, but dont do anything???

Please help… can I control the external move from within a different file or not?
