Does anybody know how to get an external movie into an swf (maybe with loadMovie or loadMovieNum) and than affect that movie with a play button, and a stop button, and a pause button) from within the file that the loadMovie was thrown into? Kind of like it happens on http://www.kodak.com//US/plugins/flash/en/corp/features/sleepingGiants/meta.swf
You can read this tutorial, it talks about loadmovie.

As for the playing and stoping, usually if you add _root to your actions, it would effect the main movie since the loaded swf is now part of the main movie and _root will now target the main movie’s timeline.
I hope I didn’t confuse you, I’m not good at explaning things. 
No… You actually clarified some things… Thanx.
