NTSC DVD September 12, 2006

There is a dvd, readily available on ebay. But it's listed as running 85 minutes, 6 minutes shorter than it's supposed run time, so I have not bought that edition. I wonder too if anyone has info, as this original 'Black Emanuelle' film seems to be quite rare. It isn't even included in the Black Emanuelle box set, which is strange. Probably a copyright problem?
