Control of movie with myclip commands

I am experinced in the control of movie clips remotely when the movie clip is part of the program and in my library.

Is there anyway to control a flash movie when an swf file is brought in via loadMovieNum(movie1.swf",2);

Is there anyway to tell it to stop when I want it to, or start or replay or even to tell when it is finished so I can then command something else to happen after it plays.

In other words, do I have any control over basic functions like you do with movie clips that are part of the flash program.
