with multisystem tv & players, i think the NTSC & PAL format is not of a problem anymore. only diff is NTSC uses a higher frame rate (29.97?) but smaller frame. den PAL uses a bigger frame but lower frame rate (25fps).
like dvds, alot will say PAL dvds are better, due to the fact that the picture is 'bigger' and frame rates is not much of an issue. to me, no diff, i just watch dvd that originate from the region, like jap movies, buy R2 NTSC, american movies also NTSC, den Europe & some other countries, PAL, note is that, there is some movies experience ghosting when switch from NTSC to PAL, due to the reduction in frame rate (u need to 'throw' some away)
