quired, just as is done with files on floppy or
hard disks.

Some DVD-Video discs with violent or adult-or-
iented scenes feature parental lock which pre-
vents children from viewing such scenes. With

lock level, playback of scenes inappropriate for
children will be disabled, or these scenes will
be skipped.
