Pro-X was a business? Group of people? Not really too sure what they were, but basically amazing cheerleaders that created videos to help cheer grow and show the awesome new things that were being done. I was so obsessed with watching it over and over in high school that I got the tshirt for Christmas one year. Funny part is that I actually had no idea there was a message board, even though I got on the website more than a few times. I probably didn't even know what a message board was back then! The DVD showed them throwing skills in cool places, but also had interviews & introductions. If I knew how to rip a dvd, I would put mine on youtube. Found a clip though from the DVD, and yes there was music like that through the ENTIRE movie!
