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.
Notes on CD-R/-RW and 
DVD-R/-RW/+R/+RW
 In some cases, CD-Rs/-RWs and 
DVD-Rs/-RWs/+Rs/+RWs cannot be 
played back on this system due to the 
recording quality or physical condition 
of the disc, or the characteristics of 
the recording device and authoring 
software. The disc will not be played 
back if it has not been correctly 
finalized. For more information, see 
the operating instructions for the 
recording device.
 Note that some playback functions 
may not work with some DVD+Rs/
+RWs, even if they have been correctly 
finalized. In this case, view the disc by 
normal playback.
 A disc created in Packet Write format 
cannot be played back.
Note on playback operations of 
DVD VIDEOs and VIDEO CDs
Some playback operations of DVD 
VIDEOs and VIDEO CDs may be 
intentionally set by software producers.

VIDEOs 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 DVD 
VIDEOs or VIDEO CDs.
Music discs encoded with 
copyright protection technologies
This product is designed to play back 
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.
Notes on Multi Session disc
 If the first session is recorded in 
AUDIO CD or VIDEO CD format, 
only the first session will be played 
back.
 The system will recognize a Multi 
Session disc as an AUDIO CD if there 
is a session recorded in AUDIO CD 
format on the disc. However, the 
system will only play back the disc if 
the first session is recorded in AUDIO 
CD format.
 This system can play back Multi 
Session discs when an MP3 audio 
track, a JPEG image file or a DivX 
video file is contained in the first 
session. Any subsequent MP3 audio 
tracks, JPEG image files or DivX video 
files recorded in later sessions can also 
be played back.
 With DATA CD or DATA DVD, the 
system will only play back DivX video 
files even if it contains MP3 audio 
tracks or JPEG image files.
