problema carica video in action script 3

[Dhavamba]

Ciao, sto facendo un gioco in flash e mi è capitato un problema molto strano: devocaricare un video, ecco tutto bene tranne che il file SWF si vede lento (solo leimmagini come la musica va a velocità normale, la creazione di un fastidiosi ritardi)non riesco a capire il motivo (se posso caricare altri video si caricano a velocità normale!) Questa è la classe

package Screens 
{
import Events.ScreenEvent;
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.events.TimerEvent;
import flash.media.SoundTransform;
import flash.utils.getQualifiedSuperclassName;
import flash.utils.Timer;
import Managers.ScreenManager;
import Managers.SoundManager;
import ScreenObjects.Button;
import ScreenObjects.SoundButton;

public class GameIntro extends Screen
{
[Embed(source = '../../lib/gameIntro.swf')]
private var Video:Class;

private var clip:MovieClip;
private var timer:Timer;
private var skipButton;
private var skipButton:SkipButton;
private var sound:SoundButton;


public function GameIntro() 
{
clip = new Video();
timer = new Timer(1000, 28);
timer.addEventListener(TimerEvent.TIMER_COMPLETE, showSkip);
}

private function showSkip(e:TimerEvent=null):void
{
timer.stop();
timer.removeEventListener(TimerEvent.TIMER_COMPLET E, showSkip);
ScreenManager.getInstance().activateBackground();
setNext(new Menu());
notifyNextScreen();
removeChild(skip);
}

override public function load():void 
{
addChild(clip);
clip.y = -5;
timer.start();
dispatchEvent(new ScreenEvent(ScreenEvent.LOADED));;

var skipButton:SkipButton = new SkipButton();
skip = new Button(skipButton);

skip.x = 440;
skip.y = 377;
skip.buttonMode = true;
skip.setClickedFunction(showSkip);
skip.width = 80;
skip.height = 26;
addScreenObject(skip);

sound = new SoundButton();
sound.x = 531;
sound.y = 372;
sound.width = 23;
sound.height = 26;
addScreenObject(sound);


}
override public function unload():void 
{
clip.soundTransform = new SoundTransform(0);
removeChild(clip);
}
override public function update(e:Event):void 
{
super.update(e);
}

}

}
