Load external files

Question

I created fifteen 300 X 250 sized movieclips. I've adjusted each movieclip into different sizes. Now I need to load 15 external files in to these movieclips. (all external files are 300 X 250).
1. When I load the external files, all the loaded files does not adjust to the resized movieclips (all external files are maintaining it original size). I need the loaded files to be resized as per the movieclips on stage.
2. Is there a short way of writing the code to load these 15 external files?
//movieclips on stage: gHolderF0, gHolderF1, gHolderF2
//external files : sample0.swf, sample1.swf, sample2.swf
I'm using this to load each external file:
var loaderPrototype:Loader = new Loader();
var selectedPrototype:URLRequest=new URLRequest("sample/sample0.swf");
loaderPrototype.contentLoaderInfo.addEventListener(Event.COMPLETE, finishLoading);
loaderPrototype.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);
loaderPrototype.load(selectedPrototype);
function finishLoading(loadEvent:Event) {
gHolderF0.addChild(loadEvent.currentTarget.content);
addChild(gHolderF0);
function errorHandler(errorEvent:Event):void {
trace("file missing");
function errorHandler(errorEvent:Event):void {
trace("file missing");

adding a child (loader or otherwise) is going to affect the scale of the child and the position of the child.  but you can't assign the exact size unless you do some intelligent scaling of the parent.  for example:
after loading is complete:
gHolderF0.scaleX=300*loaderPrototype.width;  // resize to 300x250
gHolderF0.scaleY=250*loaderPrototype.height;
but that really makes no sense.  you may as well resize the loader directly:
loaderPrototype.width=300
loaderPrototype.height=250;
