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.

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.
