I recently made a rip of Winston Churchill High Schools Showstoppers 2006 competition set. You should be able to download the whole video here. But if that doesn't work, I am making a youtube group with all the numbers so you can watch them in your browser (individually uploaded, so give them a few hours).
So yeah, if your a cool ex-showstopper and want to see some coolness, check it out. A special thanks goes to Rami A. for letting me rip the dvd from him.
Oh, and by the way, if you can't play the original file, you probably don't have Xvid installed, the easiest way to make that work is to download the vlc player from videolan.org.
UPDATE: It seems most people are having problems with the full video link, just right click on it and save it to your computer, then try to play it, or use the youtube group (as everything should be up there in the next 10 minutes). Also note, I didn't make the youtube group exclusive, so if you have a youtube id, please join it, and feel free to upload other Showstoppers videos.
