Video problems

programming flash
1

Hi,
I have a small video player in a flash page, it works but when I go to another frame (or page) then the video is still playing in the background, how can I get it to stop playing when I leave that frame. Also, I need to be able to go back to that frame and play through the videos again. Thanks, here is my code


var videoConnection:NetConnection = new NetConnection();
videoConnection.connect(null);

var videoStream:NetStream = new NetStream(videoConnection);
videoStream.play("video/vid1.flv");

var video:Video = new Video();
video.attachNetStream(videoStream);

//ADD VIDEO TO STAGE/MOVIE CLIP
videoplayer_mc.addChild(video);
video.width = 640;
video.height = 360;
video.x = 20;
video.y = 20;

var metaListener:Object = new Object();
metaListener.onMetaData = onMetaData;
videoStream.client = metaListener;

function onMetaData(data:Object):void {
    vid1_btn.addEventListener(MouseEvent.CLICK, playMovie);
    vid2_btn.addEventListener(MouseEvent.CLICK, stopMovie);

}

function playMovie(event:MouseEvent):void {
    videoStream.play("video/vid1.flv");
}

function stopMovie(event:MouseEvent):void {
    videoStream.pause();
}
