i downloaded them. the introductory ones are very interesting about the lineage of shito-ryu and its katas etc. however, the actual videos are short, rushed and whilst well performed provide little in the way of information beyond the basic form of the kata.
a better resource if you interested in kata would have to be www.karateonline.org
- videos of all major kata, international competition footage of them too, along with loads more stuff and its FREE!!
