Yeah, while I wouldn’t advertise it on the forum openly, I personally think that if you’ve bought any home video release, then a 35mm restoration project like 4K77 is fair game.
Granted, that’s technically against forum rules, so like I said - I wouldn’t advertise it.
If you own the 2006 GOUT DVD, though, you’re for sure in the clear to get GOUT-based projects like Dark_Jedi’s anamorphic cleanups and HD upscales.
