You will never find an official sanction interpretation from KKW the Dart Fish DVD's of the PoomSe's are the best quality productions of the forms ever made however they refuse to make new ones since they started the international master instructor license training and test outside Korea since they made many changes to the PoomSe's they don't want to give it to you in a dvd they want you to pay to attend a seminar.
That's not true. That whole paragraph is fiction. The Dartfish DVD set is not the most current official Kukkiwon DVD set, nor is it "the best quality." The set was produced in 2003.The so called "many changes" to poomsae is a popular myth spread by the uninformed. Current Kukkiwon poomsae has had very liitle changes since it was created in 1972.
Here are some good sources:
1. The Explanation of Official Taekwondo Poomsae – by Ik-Pil, Kang. This is an excellent
book on modern Kukkiwon poomsae. It’s more detailed than the official Kukkiwon text, which I
would also recommend. The author, GM Ik Pil Kang, 8th Dan, is vice chairman of the education
committee of the Kukkiwon. Price: $30
2. The Textbook of Taekwondo Poomsae – published by the Kukkiwon. This is a good
textbook, which accompanies the official Kukkiwon poomsae DVD set. It’S very close in design
and detail to GM Ik-Pil, Kang’s book. $37
3. What is Taekwondo Poomsae, by Kyu-Hyung Lee. This books comes with a DVD. The
author Kyu-Hyung Lee, 9th dan, is one of the world's pre-eminent poomsae teacherrs. He's
professor at Keimyung University in Korea and was head coach of the Korean national team. He was just named president of the Kukkiwon.
