URL Request

Hi

How do you load a DivX movie into a swf animation?

I know this is how you load a swf.

var swfLoader:Loader = new Loader();
var bgURL:URLRequest = new URLRequest("xx.swf");

swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadProdComplete);
swfLoader.load(bgURL);
holder_mc.addChild(swfLoader);

function loadProdComplete(e:Event):void 
{}

When I replace the URLRequest(“xx.swf”); with URLRequest(“xx.DivX”);
I get this error:
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.

Can someone please help.
