FULL Browser Issue

Question

Hello: I am in need of someone's expertise Please...
I have an AS2 .fla with all of my stage items on the timeline as opposed to inside a container swf. Hence, I must chose Center vertical and Horizontal options in the HTML alignment options when publishing in order for my movie to be perfectly centered in the middle of the browser. I would like to have a FULL Browser Background Image, however when I try using the following code, my background ("bg") does not fill the entire browser.
Can someone please tell me what I am doing wrong and if it is even possible to have a full browser background image while still using CENTER alignment in the HTML publish settings? I have tried the following code with and without the Stage align settings and with the xy coordinates centered-still no luck!
bg.Stage.align = "TL";
Stage.scaleMode = "noScale";
bg._width =Stage.width;
bg._height =stage.stageHeight;
bg.x = 0;
bg.y = 0;

I really don't know why this one project is giving me so many issues. Got my external swf cenetered- now the movie dissapears on resize
. I can still hear the music playing from the external swf though:
var swfLoader:Loader = new Loader();
holderMC.addChild(swfLoader);
var bgURL:URLRequest = new URLRequest("index2.swf");
swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadProdComplete);
swfLoader.load(bgURL);
function loadProdComplete(e:Event):void {
     trace("file loaded")
function resizeHandler(e:Event):void
bg.width = stage.stageWidth;
bg.height = stage.stageHeight;
swfLoader.x = (stage.stageWidth - swfLoader.width) * .5;
swfLoader.y = (stage.stageHeight - swfLoader.height) * .5;
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.addEventListener(Event.RESIZE, resizeHandler);
stage.dispatchEvent(new Event(Event.RESIZE));
