external preloader problem

[t0by]

Hi,

I've got a preloader, which loads an external SWF into a movieclip.
The problem is that the external SWF starts playing while de preloader is still loading.
This is the code I use:

var mcl:MovieClipLoader = new MovieClipLoader();

var mclL:Object = new Object();

mclL.onLoadProgress = function(target,loaded,total) {
	myprogress._xscale = Math.round((loaded/total) * 100);
}

mclL.onLoadComplete = function() {
		myprogress._visible = false;
		base._visible = false;
}

mcl.addListener(mclL);

mcl.loadClip("V:/movie.swf",holder);

any ideas?

thanks,

toby
