Similar but not the same. A Region 4 DVD will not play on a Region 2
player, but a Region 0 disc will play on any DVD player.
That indicates to me that the disc itself is the same the world over,
*except* for the region-coding, which is only necessary in order to
prevent large-scale personal or grey imports. It necessarily follows
that "PAL", "Secam" or "NTSC" is not the big issue it might seem.

Music DVDs are frequently authored in Region 0 coding.

I didn't think he meant that. I thought he meant a player that would
play any disc. They are available. I've got one.
