Anyone ever purchase these DVDs? They are pretty expensive and I am not sure I want to spend around $300 if they aren't worth it. I have the Mike Swain groudfighting DVD and it is very good. I also have some other Judo DVDs, but they are from France and they only work on my portable player, it has english dubbing. They aren't bad, but I would like some DVDx that would play on my regular DVD player so both my wife and I could practice while watching on our regular TV. It's kind of hard to practice watching a 7 inch screen. Any thoughts?
