Re: Blu-Ray vs DVD
Star Trek VI is also extended on DVD; there are actually two versions of this extended cut, one on the single DVD release and one on the double DVD release. The Blu-Ray is the only time the theatrical version has been made available on home video, AFAIK.
Plus, I believe the Blu-ray is the only version with the original aspect ratio.
