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.
Assuming he has the GOUT, but he’d have to buy the 2006 SEs to get the 2006 GOUT that comes with it.
Can confirm though, that GOUT upscales really are pretty good experiences.
