On the first page there's a image that you can click which starts a movie...
By looking at the source I found that the image was called something like 1stpage.mov, and the movie was called "L-whip.mov" I then asked my browser to download
http://www.dancetutor.com/L-whip.mov which it did, and I've now got it on my disk.
I guess all the other ones you want can be downloaded the same way...
The static image was the "SRC=" part of the OBJECT, and the actual movie was the "HREF=" part.
Hope this helps...
Cheers!
