Problem with stopping a loaded AS2 swf from AS3

Hi

I really need help on this. I have an As3 swf that loads an AS2 swf but when user clicks and button it should the AS3 movies should unload the as2 movie and stop all the sounds and scripts running in AS2 movie.

I am loading the AS2 swf in a loader and then simply removing the loader from the display list to stop AS2 actions and sound. BUt this is not working and even after removing the AS2 movie from display list it still keeps playing in the background.

Can anypone please help me on this?

Thanks
