DVD-ROM Drive Information
(on selected models)
The DVD-ROM drive allows you to view and create your own CDs
and DVDs. You can purchase an optional DVD viewer software to
view DVD titles.
Regional Playback Information
Playback of DVD movie titles involves decoding MPEG2 video, digital
AC3 audio and decryption of CSS protected content. CSS (sometimes
called copy guard) is the name given to the content protection
scheme adopted by the motion picture industry to satisfy a need to
protect against unlawful content duplication.
Although the design rules imposed on CSS licensors are many, one rule
that is most relevant is playback restrictions on regionalized content. In
order to facilitate geographically staggered movie releases, DVD video
titles are released for specific geographic regions as defined in “Region
Definitions” below. Copyright laws require that all DVD movies be
limited to a particular region (usually coded to the region at which it is
sold). While DVD movie content may be released for multiple regions,
CSS design rules require that any system capable of playing CSS
encrypted content must only be capable of playing one region.
IMPORTANT! The region setting may be changed up to five times
using the viewer software, then it can only play DVD movies for the
last region setting. 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 at the expense of the
user.
