Hi there,  
I’m using BitmapData to duplicate a mc.

import flash.display.\*;  
function duplicateMC(mc:MovieClip, mc2:MovieClip) {  
var mcBMP:BitmapData = new BitmapData(mc.\_width, mc.\_height, true, 0x00FFFFFFFF);  
mcBMP.draw(mc);  
mc2.attachBitmap(mcBMP, this.getNextHighestDepth());  
}

duplicateMC(mc\_container.mc\_loader, mc\_container.mc\_loader\_bitmap);

The movie clip I am duplicating loads in another movie clip swf.  
This works well, but the bitmap duplication of the movie clip is jaggered and pixelated - this also needs to zoom in.  
I am using Actionscipt 2.  
Having searched around, I am aware of:

forcedSmoothing  
and  
mc.\_quality = “BEST”  
Neither of these seems to be the answer - any advice would be much appreciated.

Best  
Fin
