Unrated version only on VHS
Even though the only way to watch the Unrated Version is the various VHS around the world, at least it is available in North America. It has become pretty rare nowadays but the NTSC unrated VHS has a yellow circle on the cover and says something like "full-length uncensored...". Beware because there is a similar VHS version without the "yellow circle" that is the Rated-R version.
I hope that the rights to this series, one day, will go to a company that will do this series justice and restore the missing footage from Parts I and V for DVD. It's a travesty that every DVD ever made is the Rated-R version.
We in North America have never had the unrated version of Part I but at very least the unrated version of Part V is available on VHS.
