Although it's bad form to judge the quality of a rip from just a few jpegs, it does look like there are some techincal issues with Spider's set.
"spider2.JPG" in Hal's second post shows ghosting in the blue lightsabre, probably a result of temporal noise reduction. Also the horizontal lines in the red are typical of the chroma upsampling error, which could incidate the video is flagged as interlaced when it would be better as progressive. Also what's going on in spider1.JPG, have the fields been blended?
