DVD-ROM Drive Information
The Notebook PC comes with an optional DVD-ROM drive or a 
CD-ROM drive. In order to view DVD titles, you must install your 
own DVD viewer software. Optional DVD viewer software may be 
purchased with this Notebook PC. The DVD-ROM drive allows the 
use of both CD and DVD discs.
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.
