Regional Playback Information for DVD
The playback of DVD movies includes the decoding of MPEG2 vid-
eos, digital AC3 audio data and the deciphering of CSS protected
contents.
CSS (sometimes called copy guard) is the name of a data protec-
tion program incorporated by the movie industry as an action
against illegal copies.
Among the numerous regulations for CSS licensees the most im-
portant ones are the country specific playback restrictions.
In order to facilitate the geographically restricted release of mov-
ies, DVD titles are released for certain regions.
Copyright laws require the restriction of each DVD movie to a cer-
tain 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 PC 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.
