It is the UOP flag (user operation prohibition). Most "DVD copier" programs who make whole copies of discs (like K9Copy or DVD 9to5 in linux or DVDShrink on Windows) remove this flag and the region restrictions, too. The DVD's author can define actions for every type of button press on the remote control, or prohibit them. Sometimes they work-around the removal of UOPs by defining the keys with invalid actions so even if the prohibition is removed, the key still doesn't work. In that case it's probably more difficult to fix it yourself. A list of the UOP flags is here: http://www.dvd-replica.com/DVD/cmd-7.php
