One other thing...

Of the people who tried to watch the video and couldn't (not including those who don't have Quicktime), did you open the page and the video loaded but didn't start?

For some reason with that particular Quicktime viewer, it is necessary to press the little "play" button (the little triangle to the right of the speaker button). I want to see if I can correct that, but in the meantime, if you tried but didn't press the button, you might be able to watch it if you do that. Also, it takes a minute or two for the video to load.
