There are many possibilities, some exciting, some meh. If it were an older generation copy of something we already have, then it wouldn't be of much interest. If it were a screen capture that didn't exist before, or an earlier generation of an already-available bootleg, that would be big. If it were a stereo grab of the 70mm mix, that would be a very important find. If it contained the Biggs hangar scene, it would induce heart attacks. It all depends on what the experts here find as they apply their respective fine-toothed combs to Antcu's initial capture. I'm looking forward to reading about it!
