Sifu Duncan Leung's DVD

Wai Jia: The Kung Fu Forum Wing Chun
1

Dear all,
I am thinking about buying Sifu Duncan Leung’s DVD on wing chun. Is it possible for you to give me some information about them?

  1. running time of the DVD, e.g. 1/2 hours or 45 minutes per DVD.
  2. Give clear explanation regarding the all forms, e.g. application and principles of wing chun.
  3. Is it value for money? I got some DVDs which give demonstration of the forms, but not how to use it.
    For instance Sifu Wong Sheun Leung’s 1/2 hour tape on wing chun is a good film. This is because I can understand and see wing chun being demonstrated. While other wing chun DVD l got show me very little about wing chun, but a lot about Thai boxing!
  4. quality of the DVD. This is because I got some DVD that were shot in dark rooms and I could not see a thing.

Please note that I am not expecting to learn wing chun from DVD or a book. I just want to know if those DVD would help me to understand wing chun better.

Thank you
