loadClip dynamic images how to smooth them?

I have been searching alot and i just cant get it right…

What i understand is that i have to duplicate the movieclip and create some kinda BitmapData version of it and it will work?

I found this example code im trying to put into my own code and it just dont work and i dont get any errors either… check this out:

first of all i load the images from external string file like this:

for(var i=1; i<=11 ;i++){ 
     imgVar = eval("myVars.img"+i);
  theURL = "img" + i;
  my_mcl.loadClip(imgVar, _root.contentHolder[theURL].bildruta);

this code adds all the images exactly where i want them… however im also going to animate each image and now i wonder how i can add smoothing to them…

i have tried to do something like this:

// notice: this is in the parent frame

import flash.display.BitmapData;
var my_mcl = new MovieClipLoader();
myListener = new Object();
myListener.onLoadComplete = function (target_mc){ 
// this code is suppose to make it smooth but i cant figure it out
myBitmap = new BitmapData(114, 114, true);
createEmptyMovieClip("target_mc", getNextHighestDepth());
target_mc.attachBitmap(myBitmap, 1, "auto", true);

Any suggestions?
