Doesn't surprise me. Although I think I remember reading the other two releases of the DC (Japanese and Korean) were both anamorphic. I wonder if they all came from the LD source and those were "fake" anamorphic conversions (ala Anchor Bay's re-releases of Tenebre/Phenomena) or if there was a superior source.
What's a fake 16x9 conversion? Zooming a letterboxed SD source?
