Preload Movie in Percentage Preloader with Load Bar tutorial?

1

I was reading this tutorial on kirupa and got it to work fine. I am now trying to switch it so instead of using the gotoAndPlay(); it will load a external swf file I have. I switched the gotoAndPlay() with _root.loadMovie(“blah.swf”); and it’s like the preloader doesn’t work. It will do the loadbar fine then it will stop for like 2 minutes then resume with the loaded movie. Is there a way to fix this?
