Curious, I had understood that it was four episodes of the 90's series, not '82. Looking at that site, I see they only say it 'appears to be' the 80's series. I would wager they're wrong.
See, for those unaware, Buena Vista/Disney bought out Saban Entertainment in the last year, and has ownership of their entire back catalogue of shows. For all their other movie tie-in releases ('Spider-Man: Ultimate Villain Showdown,' 'Spider-Man: Return of the Green Goblin,' 'Daredevil vs. Spider-Man,' 'X-Men: The Legend of Wolverine'

, they used episodes from the assorted 90's Saban series. I don't see why they'd break step with this release.
