By following your link to the Blackstar site it's still showing the release date for the second disc as being in May and their appears to be a problem with the undubbed episodes.
This, along with the removal of the first 3 extras you've mentioned have me a bit confused. Can you advise please ?
Many thanks

About your questions -
1) BlackStar have made a mistake re: the release date of the 2nd DVD. They're going to correct it, but they only do a weekly update. By Friday 29 March, it should say 22 April 2002 for the release date for both DVDs 1 and 2.
2) The problem with the undubbed episodes is just a naming issue - the original suggested English names have been written on the page, but these names have now changed.
The episodes will still appear as planned - no problem there - they've just been renamed. Again, this issue should be fixed in their update this week.
3) The removal of the 3 extras, i.e. the Masaaki Sakai interview and the BBC "I Love 1979" and "I Love Kung Fu" clips - this is still the case.

Anyway - to sum up - the first 2 DVDs will be released on 22 April 2002, and they will both contain an unseen episode, along with cast biographies, photo galleries for each episodes, and web links. Also, all 4 episodes on each DVD will be digitally enhanced.

Hope this helps.

But only for a minute !!
