At end of loaded movie clip do something

ive got a load of swfs that have been given to me, i am loading and unloading them in to a flash movie using loadMovieNum('flash/url.swf,‘1’); i cant edit the swf’s.

I want the flash movie which is loading the swf’s to go to and stop on frame 1 when the loaded movie (swf) has reached its end.

again i cant edit the swf’s.

any ideas?
