Bitmaps won't smooth.

Hello again,

I'm loading some external images and trying to get them to smooth, but for some reason it's not happening. i've been trying everything i can find on the internet over the past 10 hours or so, and nothing's worked.

The code on my movieclip (first frame) is:

var Ldr:Loader=new Loader();

var UrlR:URLRequest=new URLRequest("myImage.jpg");

Ldr.x=340

Ldr.y=0

addChild(Ldr);

Ldr.load(UrlR);

all that works fine for getting the image on the stage.

i tried many variations of the following (immediately after the above code):

var myBitmap = new Bitmap(Bitmap(Ldr.content).bitmapData, "auto", true);

OR   Bitmap(Ldr.content).smoothing = true;

ETC.

I also tried:

stage.quality = StageQuality.BEST;

//on my first frame of main timeline, but my images were still jagged

my images are very high-res, so i know it isn't a resolution issue. anyway, they look crappy when they're sized down too. also, i'm pretty sure smoothing is the issue, because i have a very similar image in the library (a detail from the same shot, and similar resolution, etc.), and it looks great when i allow smoothing in the bitmap properties panel.

anyone know what's missing in my code?

thanks!
