All great questions. I took the image from the old "two-episodes per disc" DVD.
So not, VHS, not "Remastered" TOS-R on DVD, and not "Remastered" TOS-R on Blu-Ray. (I think it should be the same as the VHS--just cleaner.)
Yes, as you surmised, I specifically wanted to know if the source was from a time before things were "messed with".
But I can only guess at the title since I only have a couple of the "two-fers".
I'm only sure that the ep is likely one of the "first five" with my favorite version of the theme.
