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 pro-
tection program incorporated by the movie industry as an ac-
tion 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 sys-
tem may only be used in one region.
Attention: 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 de-
sired, shipping and resetting costs will be
billed to the user.
