I wasn't impressed with this DVD. It says it is from beginner to black belt so I was expecting something more along the lines of the book of that title by Gulshan Sahota, which is pretty good.
However, as a brown belt, I didnt get anything from it, aside from viewing the kata at full speed, which I can get from my sensei anyway. I suppose I was looking for more indepth technical analysis - hips, for example, as that is so key to karate - but it was lacking. A technique is shown slowly and then quickly, without much dialogue of any insight at all. Also, the kata only go up to Heian Godan; there is no mention of Tekki Shodan or Bassai Dai. Kumite is not covered well at all. I had to admit I was a bit unsure how 'shotokan' this dvd was.
As to its relevance for a beginner, I guess it is a handy resource in that you can watch it over and over on your dvd, but I found each technique was covered very briefly. The film quality's not great either - I could get a camcorder and record my sensei and it would be of comparable quality.
All in all, I would rather refer to a book to remind myself of techniques in between classes than have this dvd. Mind you, I suppose it would just be better to attend another lesson instead...
