Preloader ignores external swf's actionscript

Hey guys

I have an External.swf file that is a video. The swf is 1135 frames long and running just fine by itself, stopping as I want when the actionscript says stop(); on the first frame and looping the end of the clip with gotoAndPlay(837).

The preloader SwfLoader.swf linked to the External.swf shows the percentage of bytes loaded as it should. However, it runs the video (sound playing in the background) while the preloader shows the loading progress I think it's because it doesn't load the first frame first.

Once the external swf is loaded, it plays the video again, still ignoring the first actionscript frame that says stop(); and the last frame gotoAndPlay(837).

Thank you.

Here is the preloader's actionscript on the first and only frame:

var txtPercLoad:TextField = null; //Create after duplication

var cMatrix:Matrix = new Matrix();
