trying to stop() loaded swf

I am loading an external swf that is just an animation. When I open a section in my app, I want that swf to stop playing. I cant manage to figure out how to stop it. Here is my function to load the swf

PHP Code:

---

var target:String = "data/clouds.swf";
var req:URLRequest = new URLRequest(target);
var ldr:Loader = new Loader();
ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, cloudsHandler);
ldr.load(req);
cloudHolder.addChild(ldr);
//then trying to stop it
function buildVideo():void
{
    var c = cloudHolder.getChildAt(0);
    c.content.stop(); //this does not work
} 


---

any idea?

PHP Code:

---

function cloudsHandler(e:Event):void{
    MovieClip(e.target.content).stop();
} 


---

I am not using it in my event handler. Its in a function that has no relation to the loader. I'll try this after my photoshop batch is done

PHP Code:

---

function buildVideo():void
{
    var c = cloudHolder.getChildAt(0);
    MovieClip(c.content).stop();
} 


---

alright i figured it out. I named the movie clip in my clouds.fla and then did c.content.cloudmc.stop();

PHP Code:

---

var myLoadedMC:MovieClip;

function cloudsHandler(e:Event):void{ 
    myLoadedMC = MovieClip(e.target.content);
}


// ...


function buildVideo():void{
    myLoadedMC.stop();
}
