Regional Playback Information for DVD
The playback of DVD movies includes the decoding of MPEG2 videos, digital AC3
audio data and the deciphering of CSS protected contents. CSS (sometimes called
copy guard) is the name of a data protection program incorporated by the movie
industry as an action against illegal copies. Among the numerous regulations for
CSS licensees the most important ones are the country specific playback
restrictions. In order to facilitate the geographically restricted release of movies,
DVD titles are released for certain regions. Copyright laws require the restriction of
each DVD movie to a certain region (usually the region in which it is sold).
DVD movie versions can be published in several regions but the CSS regulations
require that each CSS decipherable system may only be used in one region.
Note
The decoding software included with your notebook may be
changed for regional DVD decoding up to five times, after which the
drive will only play DVD movies for the region setting last entered.
Changing the region code after that will require factory resetting
which is not covered by warranty. If resetting is desired, shipping and
resetting costs will be billed to the user.
