I might be buying a mint condition copy of the Widescreen Edition of Star Wars (1977) on LaserDisc from a gentleman who is slowly selling his LaserDisc Collection but I am unsure if the edition he is selling is the Technidisc Pressing from 1993. How can I tell if it is or not? It has the 20th Century Fox Logo instead of the CBS Fox Video Logo and the gatefold says 1992 but aside from that I’m don’t know where it would confirm it is the Technidisc Pressing.
It took me a long while to find one, but you’re already on the right track. Certain earlier Fox widescreen discs like SW were quietly reissued in cleaner or fixed transfers using the same Special Widescreen Edition covers but with the logo replaced by the Fox one. (DIE HARD is this way too.)
For the Technidisc, you want to find one that says disc and jacket made in the USA on the rear. But sometimes this can be inaccurate. The only definite way to tell is by reading the mint marks on the actual discs themselves. These are codes stamped on the inner ring just like the deadwax codes of an LP. Just match to the Technidisc numbers on the lddb listing page and you will be set.
Keep in mind though, most pressings out there are Mitsubishis. Good hunting!!
