Query: Kenpo, or whatever's convenient

I studied Kenpo in a dojo (AA Universal) for 2 years and this didn't resemble anything I learned. First, the instructor explained how you don't have to worry if you can't kick someone's face, you'll simply kick them in the groin and he'll bend over, the next kata starts with a kick over his head. Also, he never explains the basics, like the difference between a reverse punch, a straight punch, any kick or even the fact that every strike is a block and every block is a strike. I could spend all day telling you what's wrong with the DVD, let's just say "save your money". I also purchased the DVDs by rank, yellow, orange, purple and blue, those were much better. You're much better off with the latter than the former.
