Original DVD release was Road Warrior print woldwide. It's sightly cut (actually it's the US theatrical cut).
New version on Blu-ray is Mad Max 2. Longer cut with extended violence, but it lacks some of Papagallo dialogue in the first part of the film.
I would like to get a script which can combine the colors of the DVD to the Blu-ray picture. Fixing the missing parts should be easy, they are only a couple of seconds.
