Stop button for a video player

I can’t seem to get a stop/ button to work… If anyone could lend a helping hand that would be great.

Here’s my code so far.

var myNetConn:NetConnection;
var myNetStream:NetStream;
var videoLV:LoadVars;

this.videoContainer._visible = false;

//-------------<VideoActivate>-----------------//
function videoActivate() {

this.videoContainer._visible = true;

//REPLACE THE .FLV HERE!!!!!!!
myNetStream.play("chasing_cars_video.flv");

this.vidProgBar.onEnterFrame = function() {
var progPos:Number = Math.round((myNetStream.time/videoLV.totalTime) * 100);
this.vidProgBar.vidProg._x = progPos;
var vidD1Percent:Number = Math.round((myNetStream.bytesLoaded/myNetstream.bytesTotal)*100);
this.vidProgBar.progMaskContainer.progMask._width = vidD1Percent + 10;
}

}
//-------------</VideoActivate>-----------------//

this.pause.onRelease = function () {
myNetStream.pause();
}

this.play.onRollOver = function () {

}
this.play.onRollOut = function () {

}
//back to scene 1//
this.play.onRelease = function () {
this.enabled = false;
initializeVideo();
videoActivate();
//play2.gotoAndPlay(2);
}

//-------------<Video>-----------------//

function initializeVideo() {
myNetConn = new NetConnection();
myNetConn.connect(null);
myNetStream = new NetStream(myNetConn);
this.videoContainer.myVideo.attachVideo(myNetStream);
myNetStream.setBufferTime(5);

myNetStream.onStatus = function(info) {
    if (info.code == "NetStream.Play.Stop" && info.level == "status") {
        this.togglePlay.gotoAndStop(2);
        myNetStream.seek(0);
        myNetStream.pause(true);
    }
}

videoLV = new LoadVars();
videoLV.onLoad = function (success) {
    if (success) {
        videoActivate();
    }
    //videoLV.load("video_info.txt");
}

}
//-------------</Video>-----------------//

//-------------<ourVideoOption>-----------------//

//-------------</ourVideoOption>-----------------//

//-------------<VideoDeactivate>-----------------//
function videoDeactivate() {
this.videoContainer._visible = false;
delete _root.vidProgBar.onEnterFrame;

}
//-------------</VideoDeactivate>-----------------//

//-------------<cancelVideo>-----------------//
//close//
this.stop.onRollOver = function () {

}
this.stop.onRollOut = function () {

}
//back to scene 1//
this.stop.onRelease = function () {
//togglePlay.gotoAndStop(1);
myNetStream.close();
myNetStream.seek(0);
videoContainer.myVideo.clear();
delete videoContainer.myVideo.onEnterFrame;
videoDeactivate();
videoActivate();
