I guess this makes me a Star Wars sucker, but I bought all three updates of the classic Star Wars DVDs [badstarwarspq, starwarsdvdep1] so I could watch the "bonus" inclusion of the original, unaltered films. But I was shocked to see the picture quality to be as bad as it is.
I've owned a DVD player since they were first released, and own several first-generation DVDs, but I have never seen a film that was encoded as badly as these original Star Wars films. Jaggy lines, macro-blocking, no 3:2 pulldown, etc. I've seen bootleg videos that are better looking than this. The films are practically unwatchable on a modern DVD player with a modern HDTV, and at this point in the lifetime of the DVD format, that is inexcusable.
