I did. It looks strange but result is the same wrong.
If say about such simple code:
var myBitmapData = new flash.display.BitmapData(bounds.width,
bounds.height, true, 0xFFFFFF);
myBitmapData.draw(video); //this is a clip with code mask and video
clip inside
var reflect=this.createEmptyMovieClip("reflect", 10);
reflect.attachBitmap(myBitmapData, 1);
reflect._yscale = -100;
reflect._x =video._x;
reflect._y =video._y+(bounds.height*2)-distance;
Result is not correct.
