DVD-Video
Movie plays, but
special features (such
as director’s notes
and other languages)
are unavailable
1. Not all DVD titles offer special features. Check the liner notes
included with the disc for a list of features.
2. If both the picture and sound are OK, then DVD drive is
functional. This means either the software or the movie title
(DVD video disc) is the source of the symptom. Try playing
another title to determine if the disc is the cause. If the
software is the cause, reinstall software.
