AS2 swf loaded into AS3 swf stop and play controls

programming flash
1

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 {
            event.currentTarget.removeEventListener(Event.COMPLETE,imageHandler2);
            loader2.content=MovieClip;
            addChild(loader2.content);
            loader2.content.stop();
            loader2.content.addEventListener(MouseEvent.CLICK,checkFrontClick2Handler);
            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::AVM1Movie@3b326a9 to flash.display.MovieClip.
