Preloader test

Ive been making a preloader which loads movies in order but if someone clicks a button while loading, the order changes and that movie is loaded first. Although it seems to work from my pc, ive been on sites which simulate downloads at different speeds and it seems full of bugs. Please could some of you have a look and give me feedback along with connection speed.

I am on Cable, and it seemed to take a while. It seemed to work though how it downloaded the MC and then moved onto the next.

Thanks for that Ethan.
The files were made deliberately large as this type of thing is quite difficult to test and it gave me a little more time.
