My take on video training is that it's about the same as watching a class. It's not interactive, but you can get teaching from the best in the world, for a fraction of the cost of a seminar. Plus, you can watch it over and over.
That being said, videos are much more beneficial if you have some background in the art or use them as an introduction.
Oh, and please be careful of sharpened blades. Read this
for some chilling stories of people who weren't careful enough!
Let me know if you'd like some suggestions on training videos.
