To much data on 1st frame

This is another preloader question. I applogize but I have look around for a couple of hours and I can not solve this problem.

I have a movie and I am use the preloader from kirupa.com called, “Percentage Preloader with Load Bar”.
In this version the preloader is on frame one and the content of the movie is on frame three. When you render the movie the preloader bar shows up immeditly and loads the content.

I am doing the same thing but when I rendar my movie, which is a 151k, I have to load though 83k first before I see my preloader.
When I look back on it I have alsways had this problem but most of the time my movies where small. Does anyone have a fix for this.
