AAC, which stands for 

Advanced Audio Coding

, is the 

audio compression technology used for MPEG-2 and 
MPEG-4. The actual format of the data and file extension 
depends on the application used to make the AAC file.
• The DVD player can play AAC files made with iTunes 

that have a .m4a file extension. 

• Files with DRM (Digital Rights Management) cannot 

be played, and files encoded with some version of 
iTunes may not play. 

WMA, which stands for 

Windows Media Audio

, is an 

audio compression technology developed by Microsoft 
Corporation. Audio content can be encoded in WMA 
format by using the Windows Media Player version 7.1.1, 
Windows Media Player for Windows XP, or Windows 
Media Player 9 Series.
• The DVD player can play WMA files.
• Use only applications that have been certified with 

Microsoft Corporation to encode WMA files. If you 
use an application that is not certified, the resultant 
files may not play properly.

The region number for the DVD player can be found on its 
rear panel. The DVD player can only play discs with the 
same region number or those marked 

ALL

. If you attempt 

to play a DVD-Video disc with a different region number, 
the message “Incompatible disc region number, Can’t play 
disc” will be displayed.
