Who ever has the uncut version on VHS

I always thought there were better films for that. Such as hard target, and Event Horizon.
My Favorite Friday is Friday the 13th Part VII: The New Blood. So have no concern over this.

What's in the uncut version that's not on the dvd release?

LIFE GOALS, MAN!!!

There is no uncut version on VHS. It doesn't exist and it never has. As a matter of fact a lot of those "uncut European/Scandinavian/whatever VHS releases" are just the R-rated U.S. theatrical version because the initial releases in other countries were cut even more by that country's censorship board.

The uncut versions of the first 8 Friday the 13th films are all lost with the exception of the first one because it was actually released uncut and uncensored in theaters in the UK I believe. Even that one there are rumors that graphic death scenes for two characters who die off-screen were originally included before being cut due to the X rating threat from the MPAA, according to IMDB Alternate Versions section. A VHS workprint of Part 7 exists. And that's it. The original elements to the films were either junked or stored somewhere that nobody knows about.

Sadly, studios never took advantage of home video back then as a way to present the full uncut versions of films that had been censored by the MPAA. Notable exceptions included Videodrome, Crimes of Passion, and 9 1/2 Weeks which were released uncut on VHS. The trend continued here and there in the 90s with big films like Basic Instinct and Natural Born Killers, hot and controversial films, not low-budget slashers. I think Hellraiser II was an exception to that. Nowadays "unrated versions" of genre films are a given when they come out on DVD and Blu-Ray.

but how? i've never heard of the uncut version on VHS?
