I’m sorry, but what is “GOUT”? I’m brazillian and can’t understand all the words! ;p
But, the video quality depends on somethings like codecs and some filters, you can “mask” it!
The GOUT refers to the 2006 DVD set that included the original unaltered trilogy as bonus discs. These were just mastered from Laserdisc so the quality wasn’t great.
Gout is also a medical reference to a type of foot arthritis so it’s a bit of a pun. (Gota is the Portuguese word I think…)
