According to author Allan Asherman in his The Star Trek Compendium resource book, there are actually two different versions of "Where No Man Has Gone Before", only one of which has been televised and it is available on VHS and DVD.

Jump over to TrekWeb for a list of the differences between the Roddenberry version & the edit that eventually made it to air (which include a voice-over set-up by Kirk). A crude YouTube featuring the changes discussed at TrekWeb can be found here:
