I have both the NTSC US box set(s), and several PAL trilogies, and, as I like to continue my SET (Special Edition Trilogy) project, I should decide if I must use the PAL laserdiscs - that, theoretically, have more vertical resolution - or the NTSC ones - that probably were mastered better.

I noted also that the NTSC image is less cropped at the sides and at the bottom, and, despite the fact that its resolution is 20% less than PAL, it shows more details… on the other hand, more different PAL edition could be used to average/median the captures, removing a lot of analog noise inherent of the laserdisc format itself. The soundtracks used will be of course taken from all the versions available.

Last thought: using the Pioneer HLD-X9 for NTSC capture, final result should be better than using any other PAL laserdisc player for capture, hence I think I will use the NTSC discs for the video part… or not?
