Excuse for my english..... : ) I hope that you understand

Hi, I have a little trouble.
In my site I have a media display with a video stream .flv.
When I go to the secction with the video and this video begin to run, I
change of section and the video still running and it doesn't be.

The action that I use to load the movie is:

on (release) {
loadMovieNum("video.swf",10);
}

And when I go to other any section apply this action: (I supose that video
stream will be stoped but still playing)

on (release) {
unloadMovieNum(10);
}



Can you help me??
What can I do???
