Actually, the original post describes a situation that isn't the Player or the Disk, but the TV's electronics that refuse to play a PAL-encoded video.
A good many flat-screens are being delivered with those electronics embedded now - they're not just refusing to play because of Region Codes, but now they can detect PAL vs NTSC encoding, and refuse to allow consumers to watch what they want.
Instead of letting the TV makers dictate what we're allowed to watch, when we go shopping, we take along a crummy li'l $30 Coby DVD player, its component cables, a couple of Region-Zero PAL DVDs and insist the sales folks hook the gear up to our first choices of flat-screens. We can see the Player pass LOAD then PLAY, and then watch the Flat-Screen display "INVALID DISK" or "NO DISK" after the Coby's flashed "PLAY". So we know it's the TV making the decision.
We get the salesman to hook it up to a different model and then others, if need be, until we find units that allow us to watch OUR entertainment on OUR schedule.
Truly, the restrictions for Region Encoding and PAL vs NTSC are nonsense - do gov'ts think the Balance Of Trade is dependent on DVD or BluRay sales? That a few tanks and fighter planes aren't the REAL cause for trade imbalances, or the real reason cash flows one way instead of the other?
