FLV inside an mc behaves strangely

I have placed an FLVplayer component inside a MC on the stage and when I’m trying to resize it, it resizes down to about a third of the size it’s supposed to!? I’m at a loss, why is this happening?

If I’m placing the FLVplayer component directly on the stage and use the exact same code it works fine… Please help!!

this is the code I’m using to resize the MC, the MC is conveniantly named mcWithVideo

function sizeMcWithVideo (event:Event):void
	mcWithVideo.width = stage.stageWidth;
	mcWithVideo.height = stage.stageHeight;
	( mcWithVideo.scaleX < mcWithVideo.scaleY ) ? mcWithVideo.scaleY = mcWithVideo.scaleX : mcWithVideo.scaleX = mcWithVideo.scaleY;
	mcWithVideo.x = (stage.stageWidth/2) - (mcWithVideo.width/2);

stage.addEventListener(Event.RESIZE, sizeMcWithVideo);
