I’d rather deal with whatever problems NTSC has than ever listen to the pitchy sped-up mess of PAL.
Not all PAL material is affected by the speed up issue and with those that are, it can be easily worked around. I live in a formerly PAL broadcasting nation, my parents are from an NTSC region - I’d rather deal with neither of the problems with both standards.
Every DVD I bought back in the day did. I would say that the ones that compensated were far in the minority. Of course, now it’s extremely easy to work around. Then? Not so much.
