The Mac dvd player does not playback dvd video discs created on a PC using nero 5. The Mac player comes up with the error "not permitted". The DVD disc is a region free Pal disc. I have found in a forum that this is an issue with Mac OS X 10.2 through 10.2.8. "The message "Not permitted" appears when you try to play a DVD-R disc. No files on the disc are visible in the Finder. This can happen when the disc was burned in a way that file permissions were not properly set on the disc." What can I do to remedy this? What file attributes does the dvd player need to see in order to play the disc? very urgent!!
