Don’t blame it all on Lucasfilm. Plenty of people don’t see any significant visual difference between DVD and Blu-ray, and assume all content on a DVD is more-or-less “DVD quality” and by extension not significantly different than Blu-ray. Therefore, because the GOUT is on a DVD, it has essentially the same visual quality as the Blu-rays. QED, or something like that. You see this all the time, it’s just particularly galling because the GOUT is so awful (which you can blame on Lucasfilm).
it’s the disease of the XXI century, people with cellphones of $400-600 and still with DVD players at home. When you can buy a cheap Blu-Ray player for 50-70 bucks
