AS2 swf loaded into AS3 swf stop and play controls

I’m using SWFbridge to load an AS2 swf into an AS3 swf. Everything is loaded fine but I can control the stop and play of my AS2 swf anymore because flash is using it as a Display object as opposed to a movie clip. I tried to make it a movieclip but I got an error that it is read only. Help?!
The AS3 file is a carousel: Here’s the code that adds the AS2 swf to the carousel and where I need it to stop.

           private function imageHandler2(event:*):void {
            carousel.addItem(loader2.content, "webinars");

I also tried casting it as MovieClip(loader2.content).stop(); which gives me this error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::[email protected] to flash.display.MovieClip.
