Looking for a Preloader for Multiple External SWFS

I was wondering if someone could help me. I’ve spent months looking for an AS2 preloader that does the following:

  1. Preloads multiple external swf files into a single movie holder.
  2. Starts automatically preloading once the parent file is launched.
  3. Contains a progress bar with % downloaded.
  4. Can be placed on a “Preload” scene.

Working on the file in Flash CS3, AS2.

I’ve looked at tutorials, scanned the web, etc. And I still can’t find the right one, or even how to make one.

Can anyone point me in the right direction?
