yes, this is the trick. libdvdcss does NOT requests the title key from the
drive!!! it crack it without the help of the drive itself!
so this check never runs, even fi exists in the drive.
my fairly new sony dvd rom has this check in the firmware, windows needed to
set the right region code to work. but libdvdcss didn't!
