Need help putting NetConnection Video into empty mc with controls

//HERE'S THE CODE:

import flash.net.NetConnection;
import flash.net.NetStream;
import flash.media.Video;

stage.align= StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;

var video:Video = new Video;

//puts the close button on the screen, "closeBtn" is the class name given when exported to actionscript
    var newcloseBtn:backBtn=new backBtn();
   
    newcloseBtn.x = stage.stageWidth - 60;
    newcloseBtn.y = 45;



//accelerometer orientation code goes here
    video.x = (stage.stageWidth- video.width) / 2;
    video.y = (stage.stageHeight- video.height) / 2;

    video.width = stage.stageWidth;// Resize video instance.
    //video.height = (stage.stageHeight - video.height) / 2;
   
   

var NC:NetConnection = new NetConnection();
NC.connect(null);// starts a connection; null is used unless using Flash Media Server

var NS:NetStream = new NetStream(NC);
var meta:Object = new Object();

meta.onMetaData = function(meta:Object){
    trace(meta.duration);
}

NS.client = meta;
video.attachNetStream(NS);

var vidArray:Array = new Array("SFN1/intro.flv", "SFN1/Stance.flv","SFN1/Safety_Fun_Learning.flv", "SFN1/Strapping In.flv", "SFN1/ Skating.flv");

introBtn.addEventListener(MouseEvent.CLICK, goIntro);

function goIntro(event:MouseEvent):void
{
    trace(vidArray[0]);
    NS.play(vidArray[0]);
    addChild(video);
    //video.height = stage.stageHeight;
    addChild(newcloseBtn);

}

stanceBtn.addEventListener(MouseEvent.CLICK, goStance);

function goStance(event:MouseEvent):void
{
    trace(vidArray[1]);
    NS.play(vidArray[1]);
    addChild(video);
    addChild(newcloseBtn);
   
   

}

safetyBtn.addEventListener(MouseEvent.CLICK, goSafety);

function goSafety(event:MouseEvent):void
{
    trace(vidArray[2]);
    NS.play(vidArray[2]);
    addChild(video);
    //video.height = stage.stageHeight;
    addChild(newcloseBtn);
}

strapBtn.addEventListener(MouseEvent.CLICK, goStrap);

function goStrap(event:MouseEvent):void
{
    trace(vidArray[3]);
    NS.play(vidArray[3]);
    addChild(video);
    //video.height = stage.stageHeight;
    addChild(newcloseBtn);
}

skatingBtn.addEventListener(MouseEvent.CLICK, goSkating);

function goSkating(event:MouseEvent):void
{
    trace(vidArray[4]);
    NS.play(vidArray[4]);
    addChild(video);
    //video.height = stage.stageHeight;
    addChild(newcloseBtn);
}

    //adds the listener for the close button
    newcloseBtn.addEventListener(MouseEvent.CLICK, closeWindow);
    //tells flash to remove the opened window (makes the close button work as it should
    function closeWindow(e:MouseEvent):void
        {
            removeChild(video);
            removeChild(newcloseBtn);
            SoundMixer.stopAll();
        }
