Aside from PAL resolution being 20% higher than NTSC resolution, from the comparison images; the unscaled but cropped war-room image I posted of the NTSC definitive collection LD, and the same scene Moth3r posted of his PAL DVD created from his French PAL LD (only scaled upwards vertically) it's painfully obvious that the NTSC definitive collection suffers from noticable detail loss - lines & sharp edges that are nearly horizontal are jagged, whereas the PAL set isn't jagged on the same lines & sharp edges.

I'm going to try and get the PAL LD set for two reasons, 20% higher image quality which helps image clarity on a projected picture, and no loss of detail on those near-horizontal edges.
