We've had that PAL vs. NTSC discussion at least two times in this thread if I remember correctly, people mostly agreed that PAL was just a different version of the NTSC master, but you can look for yourself if you want: https://www.google.com/search?q=pal%20site%3Ahttp%3A%2F%2Foriginaltrilogy.com%2Fforum%2Ftopic.cfm%2FStar-Wars-GOUT-in-HD-using-super-resolution-algorithm%2Ftopic%2F17552%2F&rct=j
One can hardly compare them, as we know they have different dimensions and any upscaling/downscaling would have a probably unknown (bad) impact on the result. Also it is very hard to match them. I don't know how Laserdisc Master (or _,,,^..^,,,_) could achieve this for his PaNup, I have already tried for an hour or more but couldn't do it.
