Preloader using loadMovie kills framerate

I am building an intro for a website. When I publish the swf with html and upload it straight to the server, i get a great framerate (~30 fps). However, when I plug the intro into my preloader, the framerate drops, and the flash player automatically sets the first part of the intro to low quality. I am using a preloader that uses a loadMovie command rather than the traditional preloader on frame 1, content on frame 2. Does anybody else know anything about the loadMovie command causing deplorable frame rates?

The links to the movie are as follows:

without preloader: http://www.abideclothing.com/intro/introbetter06_content.html

with preloader: http://www.abideclothing.com/index_03.html

(if your machine is really fast, the one with a preloader might not kick it down to low quality, but it does on my athlon 2000 machine)
