I believe the master is looking for a non-MST'd version. Unfortunately, they stopped offering non-MST'd versions of the films on the DVDs pretty early on, and I do not believe the "Red Zone Cuba" DVD has it. No description I have found mentions the uncut movie on the DVD.
Really unfortunate, because that is why I have the non-MST versions of a couple of films (like "The Creeping Terror").
The MST3K Collection Volume 1 does have the non-MST'd versions of "The Skydivers" and "The Creeping Terror."http://www.amazon.com/exec/obidos/tg/detail/-/B00006RJCL/badmoviesorg
