Note on playback operations 
of DVDs and VIDEO CDs
Some playback operations of DVDs and VIDEO 
CDs may be intentionally set by software 
producers. Since this system plays DVDs and 
VIDEO CDs according to the disc contents the 
software producers designed, some playback 
features may not be available. Also, refer to the 
instructions supplied with the DVDs or VIDEO 
CDs.
ALL
Music discs encoded with 
copyright protection 
technologies
This product is designed to playback discs that 
conform to the Compact Disc (CD) standard. 
Recently, various music discs encoded with 
copyright protection technologies are marketed 
by some record companies. Please be aware that 
among those discs, there are some that do not 
conform to the CD standard and may not be 
playable by this product.
Note on DualDiscs
A DualDisc is a two sided disc product which 
mates DVD recorded material on one side with 
digital audio material on the other side.
However, since the audio material side does not 
conform to the Compact Disc (CD) standard, 
playback on this product is not guaranteed.
Cautions when playing a disc 
that is recorded in Multi 
Session
•  
This system can play Multi Session CDs 
when an M P 3 file (JPEG file) is contained in 
the first session. Any subsequent MP3 files 
(JPEG files) recorded in later sessions can 
also be played back.
•  
If audio tracks and images in music CD 
format or video CD format are recorded in the 
first session, only the first session will be 
played back.
•  
When playing a disc which contains audio 
tracks in music CD format, MP3 files and 
JPEG files, only the audio tracks in music CD 
format can be played back.
•  
CD-R and CD-RW discs recorded in multi-
session that have not ended by “closing the 
session” are not supported.
•  
With CD-ROMs/CD-Rs/CD-RWs that 
contain DivX files in addition to MP3 files or 
JPEG files, the system plays only the DivX 
files.
