External SWF only plays first few frames then loops

Question

Help!  I've been working on this for the past few weeks.  Have read everything I can read.  Have tried everything I that has been posted.  And still I can seem to get a simple external swf to load and play using AS3.  I have tried numerous ways with the same results everytime.  Here are a few of the scripts I have tried.  What I would like to have happen is to have one main timeline where I load sequentially external SWF files - there is no interaction required - it is a presentation that includes video and other Flash SWF files that I have created.  Now I just want them all in one flash file.  I had no problems with AS2 doing this, but I'm sure having fits with AS3!  please HELP - my deadline is this week and I'm not even close to being ready.  THANKS!
var myLoader:Loader = new Loader();                   
var url:URLRequest = new URLRequest("script1_3.swf");                                  
addChild(myLoader);
//var begin:MovieClip;
//var beginLoader:Loader = new Loader();
//beginLoader.contentLoaderInfo.addEventListener(Event.INIT, beginLoading);
//beginLoader.load( new URLRequest("start1_3.swf") );
//function beginLoading(evt:Event):void {
//thisMovieClip = MovieClip(beginLoader.content);
//stage.addChild(thisMovieClip);
//thisMovieClip.play();
//import flash.display.*;
//import flash.net.URLRequest;
//import flash.events.Event;
//var _swfLoader1:Loader;
//var _swfContent1:MovieClip;
//loadSWF1("script1_3.swf");
//play();
//function loadSWF1(path:String):void {
//   var _req1:URLRequest = new URLRequest();
//   _req1.url = path;
//  _swfLoader1 = new Loader();
// setupListeners1(_swfLoader1.contentLoaderInfo);
//  _swfLoader1.load(_req1);
//function setupListeners1(dispatcher1:IEventDispatcher):void {
//  dispatcher1.addEventListener(Event.COMPLETE, addSWF1);
  // dispatcher1.addEventListener(ProgressEvent.PROGRESS, preloadSWF1);
//function preloadSWF1(event:ProgressEvent):void {
//   var _perc:int = (event.bytesLoaded / event.bytesTotal) * 100;
//swfPreloader1.percentTF.text = _perc + "%";
//function addSWF1(event:Event):void {
/// event.target.removeEventListener(Event.COMPLETE, addSWF1);
//  event.target.removeEventListener(ProgressEvent.PROGRESS, preloadSWF1);
//  _swfContent1 = event.target.content;
// _swfContent1.addEventListener("close", unloadSWF1);
// addChild(_swfContent1);
//function unloadSWF1(event:Event):void {
//  _swfLoader1.unloadAndStop();
//removeChild(_swfContent1);
//  _swfContent1 = null;

Believe me, I'm feeling the pressure!!!  I sent a screen shot and it got kicked back!!!! 
here is the code I'm using in the main time line:
var myLoader:Loader = new Loader();                    
var url:URLRequest = new URLRequest("script1_3.swf");  // THIS can be any SWF file - same results
myLoader.load(url);                                    
addChild(myLoader);  
The only thing that is in the main time line before this is a page roll over effect component - and if I remove that I have the same problem!  I'm sorry, I don't know what else to provide you without giving you my fla files which I tried to send and they were kicked back!!!
HELP!
