A few years ago, I completed a custom 3 DVD set with a widescreen reconstruction of the Special Longer Version and a copy of the Theatrical Cut with the orignal subtitle typeface. I might have also used the LD audio for the TC, but I don't remember. Unfortunately, my DVD+R DL backups went bad and the copies I thought I'd made to my external HD weren't there. And, to add insult to injury, the few people I sent physical copies to (I think there were only 3) couldn't be bothered to help me create backups from their discs. Swell :/

Now that my sob story is finished, one thing I did notice at that time (and did save as a screengrab) was an alternate shot used during the mindmeld scene on Vulcan. The Deleted Scenes on the '02 DVD and the LD featured one version, while the '09 DVD/BD and Director's Cut featured another. The hand placement and Spock's expressions are slightly different.

(Please note this screengrab was after I'd completed my "lost" custom disc and does feature the replaced subtitles.)

I wonder which is true to the original Theatrical Cut. I lean toward the first.
