Unless I'm mistaken, I've noticed dotcrawl on NTSC too. I don't know
if I've seen rainbow effects on NTSC before but on PAL yes it can be
very bad (especially pictures of skyscrapers that just go totally

If you do a google search for 'PAL vs NTSC' you do get an overwhelming
number of pages in support of PAL. Maybe this is just a widely held
but ignorant point of view.
Personally, as someone who is used to the 4% speedup (but smoothness)
of PAL, when I watch pulldown'd NTSC I see a slightly visible speed
up, slow down, speed up, slow down, all the time. This really annoys
I know you are an expert on this stuff, so I don't really want to
