The iPad doesn't support Flash video. You can do one of two things:
(1) Go into your BallroomDancers.com user settings and change your video viewing preferences to Quicktime. Note that this will affect your viewing preferences across all devices.
(2) Go to http://mobile.ballroomdancers.com/ instead. This mobile website was designed for the iPhone, but looks pretty good on the iPad, too. And it'll play our videos. You can even add an icon to your home screen to make it function like an app.
