If you want to watch the 2 missing scenes that this "special edition version" doesn't feature, go to sensory control and watch the movie in "interactive mode". Then, you get to see the two missing deleted scenes:
-T-1000 scanning john's room, and
-The alternative ending.
Those are the missing scenes completing the "special EXTENDED version"
Reviews: DVD Talk also has a review of
Terminator 2: Extreme dvd by Jason Bovberg.
