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. 

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.
