I'm quite sure the THX PAL laserdisc don't use NTSC masters - as they often have more resolution than GOUT DVDs, but almost sure the original masters used are the same, as it seems there are the same faults...

The problem is it's almost impossible to align the PAL and NTSC perfectly... but that's "almost" is that what is interesting...

Take a look at the link I added to the first post to have an idea: the captures were not high quality, and not perfectly aligned, but result is everything but bad!

It will be interesting to find a movie which has not any HDTV version, but has PAL and NTSC versions - both laserdiscs or both DVDs - to test.

Anyone who happens to have PAL and NTSC versions of the same movie, that are perfectly spacially aligned each other, and want to share some clips (10/20 seconds long, lossless), please P.M. me as I'd like to test this script further.
