Where did you hear that? As far as I know all players must support all possible formats.

Which could be PAL and/or NTSC.

I assume the players can handle that, but most of the TVs in NTSC Country would not proper display PAL, which also should be gone since all the TVs are selled worldwide.

Who says I heard it from anyone? I have personal experience with it since my PS3 refuses to play certain content.

Where do you live, FreaQ? In NTSC-land it is well known that we have to avoid 1080i50 when looking for Region Free imports on UK sites.

But if you want a reference, Page "6-7" of Blu-ray Disc Demystified.
