Way out was never "filmed". It was "taped' the same way that 6 season two Twilight Zones were taped (Static, Lateness of the Hour, Night of the Meek, The Whole Truth, Twenty Two & Long Distance Call).
The original Way Out tapes were donated to the Museum of broadcasting (Now Paley Media Center) by David Susskind. That means their videos should look pretty clean, but they are tape and wont be quite as crisp as film. More like the soaps of the 50's and 60's might look. I have never seen them, but based on what I know, this would be the case.
I understand CBS may also have 3 episodes, but I'm not positive on that. As I said before, I have to wonder that even if anyone influential DOES want to release Way Out, how much trouble would they have prying the tapes from Paley Media Center. I get the impression that once they have a copy of something, it is locked within their walls and only those visiting the center will ever see them. I hope my impression is wrong. I tried to make some inquiries with them but they never responded.
