The German BDs have english Dub, but no english sub. And I would say that the BDs not look like the DVDs.
Here is a comparison between german BD and UK DVD for "The Big Boss" the upcoming comparison may be "Game of Death"
The same look have the BDs from Hong Kong and the BDs from Germany of "Game of Death", "Fist of Fury", "The Way of the Dragon" and "The Big Boss"
