I had the same problem a while ago, here was my final solution
[as]
import flash.display.BitmapData;
import flash.geom.Rectangle;
import flash.geom.Point;
import flash.geom.Matrix;
//
function staticCloneMC(target, mc, padding) {
var bounds = mc.getBounds(mc);
var offset_y = padding;
var offset_x = padding;
bounds.height = bounds.yMax-bounds.yMin;
bounds.width = bounds.xMax-bounds.xMin;
var w = bounds.width+offset_x;
var h = bounds.height+offset_y;
bounds.x = bounds.xMin-offset_x/2;
bounds.y = bounds.yMin-offset_y/2;
var lvl = target.getNextHighestDepth();
var clip = target.createEmptyMovieClip("dupe_"+mc._name+"_"+lvl, lvl);
var holder = clip.createEmptyMovieClip("holder", 1);
clone_bitmap = new BitmapData(w, h, true, 0x00000000);
holder.attachBitmap(clone_bitmap, 1, "auto", true);
clone_bitmap.draw(mc, new Matrix(1, 0, 0, 1, bounds.x*-1, bounds.y*-1));
holder._x = bounds.x;
holder._y = bounds.y;
clip._x = mc._x;
clip._y = mc._y;
clip.bitmap=clone_bitmap
return clip;
}
function animCloneMC(target, mc, padding) {
var lvl = target.getNextHighestDepth();
var clip = target.createEmptyMovieClip("dupe_"+mc._name+"_"+lvl, lvl);
var holder = clip.createEmptyMovieClip("holder", 1);
clip.mc = mc;
clip.padding = padding;
clip.onEnterFrame = function() {
var bounds = this.mc.getBounds(this.mc);
var offset_y = this.padding;
var offset_x = this.padding;
bounds.height = bounds.yMax-bounds.yMin;
bounds.width = bounds.xMax-bounds.xMin;
var w = bounds.width+offset_x;
var h = bounds.height+offset_y;
bounds.x = bounds.xMin-offset_x/2;
bounds.y = bounds.yMin-offset_y/2;
clone_bitmap = new BitmapData(w, h, true, 0x00000000);
holder.attachBitmap(clone_bitmap, 1, "auto", true);
clone_bitmap.draw(mc, new Matrix(1, 0, 0, 1, bounds.x*-1,
bounds.y*-1));
holder._x = bounds.x;
holder._y = bounds.y;
};
clip._x = mc._x;
clip._y = mc._y;
clip.bitmap=clone_bitmap
return clip;
}
