_root.loadMovie() equivalent?

I need the functionality that “_root.loadMovie()” provides in every other Flash version!!

I CANNOT utilize “stage.addChild(Loader.content)” as a workaround. A Flash 6 .swf is involved whose script does NOT execute properly under an AS3 umbrella. In fact, this particular Flash 6 .swf CRASHES Flash CS3 when addChilded!! However, this crashing problem does not occur when I use _root.loadMovie() instead.

Plus, FlashVars are preserved with _root.loadMovie().

so is there an equivalent? something like “this.root.swapWith(Loader.content);”?

It’s VERY important to me and I would be extremely grateful for any help.
