Expand flash movie via Actionscript

Wondering if anyone has any suggestions here, I must be missing something obvious…

I’m trying to make a flash movie that expands on rollover, “pushing” down the rest of the HTML page the movie resides in. On rollout, it should go back to it’s original size. Ideally, this expansion would be animated, and I could adjust the speed to sync with the JS expansion of the DIV the movie resides in.

For the pushing part, I’m using a javascript call to a scriptaculous method, which works well when triggered through Flash’s external interface. Problem is, I can’t seem to get the movie itself to resize. I’ve tried changing the “stage.stageHeight” attribute, to no avail.

Surely there is a way to change a flash movie’s height at runtime. But how?

Thanks,

Jeff
