Stoping External Playback Video

Hi all,

I’m having a huge problem in my flash file. here is the thing:

I have a menu and every time a user clicks a button it takes him to a jey frame where there is a external movie playing. but if he clicks on the menu again it takes him to the other movie but the first movie audio dosen’t stop.

So here are my two doubts:

Is there anyway that I can control my external movie via AS so I can Pause and Play it?

How can I take the audio off when the user goes from one movie to the other?

Thanks for the help.
