Hi all, This has been bugging me for some time. What actually is progressive scan and who should use it? I hear a lot about the NTSC format being mentioned but as I do not have any region 1 discs so at the moment it hasn't bothered me. I know it makes the picture sharper, but for what? Pal or NTSC? Or both? It's kinda confusing to me...hope someone can clarify?
