DVD - THis was Fox's second release of the movie shortly after the original. Original was non-anamorphic with no special features. This second version had alternate ending, lots of special features and most importantly was anamoprhic.
BD - This is an MPEG-2 25GB disc. I'm not positive, but i think this was a DTheater release and uses the same transfer. Either way, not the best transfer in the world, but a clear improvement over the DVD. I got this during a BOGO and actually paid less for it than I paid for the first two DVDs. Yup, Fox pricing was expensive even back in the earlier DVD days!
