MovieClip Preloader keeps looping movie

Question

MovieClip Preloader keeps looping movie
I made a MovieClip preloader and everything workes fine.  The problem is the movie that I am loading  keeps looping.  Is there any way to stop this from looping?  I used  Flash CS5, AS2.
Here is the code that I am using:
bar._visible = false;
border._visible = false;
this.createEmptyMovieClip("container", "100");
my_mc = new MovieClipLoader();
preload = new Object();
my_mc.addListener(preload);
preload.onLoadStart = function(targetMC) {
trace("started loading "+targetMC);
container._visible = false;
bar._visible = true;
border._visible = true;
pText._visible = true;
preload.onLoadProgress = function(targetMC, lBytes, tBytes) {
bar._width = (lBytes/tBytes)*100;
pText.text = "% "+Math.round((lBytes/tBytes)*100);
preload.onLoadComplete = function(targetMC) {
container._visible = true;
border._visible = false;
bar._visible = false;
pText._visible = false;
trace(targetMC+" finished");
//default image
my_mc.loadClip("main.swf", "container");

Thank you for responding
The stop action stopped the movieclip preloader from looping the movie, but now it shows a black screen at the end instead of the last frame of the movie.
