Huh? If it's not anamorphic you have to reduce the vertical resolution (without violating DVD spec). Or do you mean that it's shot at 1.85:1 and remastered to anamorphic 1.78:1 for DVD so they get to use the full vertical resolution compared to a typical 'Hollywood' anamorphic 2:35:1?
Sorry, should have been clearer. What I meant was that it wasn't 2.35:1 or some other "significantly wider than 16:9", resulting in black bars.
The original aspect of the movie is 1.85, don't know if it's cropped on the DVD, but I guess so since it's a perfect 16:9 fit. Looks stunning (sounds good too).
Cheers
