Well (to put that to rest), there are two types of region coding in use on DVDs. The first is the one we're talking about here ... which is a code in the files that tells the DVD player which region the disk is. Early "unlocked" players were simply patched to accept any region.
The second type is code in the menu system that queries the region code and then acts on it. Early players returned '0' for this function ... and the disks were coded to not play.
The fix for this was players that you could change the region on ... and "unlocked" players of this type allow you to set the region an unlimited number of times. "locked" players usually let you set the region some small number of times.
It turns out I was wrong ... even though the k3b stuff I read said it was using cdrdao, a bit more investigation proved it was using mkisofs and growisofs instead. The both have large man pages, but nothing in them regarding the setting of region codes.
I really don't want to have to replace my existing dvd players, that is dumb, then I have a nice programmable system here.
Dave.
