DVD Region Codes
The Blu-ray™ Disc player and many DVD discs
are coded by geographic region. These region
codes must match in order for the disc to play.
If the region code for the DVD disc does not
match the region code for the player, the disc
will not play.
DVD Audio Support
When a DVD-Audio disc is inserted in the
Blu-ray™ Disc player, the DVD-Audio title on the
disc is played by default (most DVD-Audio discs
also have a Video title, but the Video title is
ignored). All multichannel program material is
automatically mixed down to two channels,
which may result in a lowered apparent volume
level. If you increase the volume level to
account for this change in level, remember to
lower the volume before changing the disc or to
another mode.
Recorded Discs
The Blu-ray™ Disc player will play CD-R and
CD-RW discs recorded in CD-Audio or Video-CD
format, or as a CD-ROM containing MP3 or WMA
files. The player will also play DVD-Video content
recorded to a DVD-R or DVD-RW disc. DVD-ROM
discs (either pressed or recorded) are not
supported.
If you record a disc using a personal computer,
there may be cases where the Blu-ray™ Disc
player may not be able to play some or the
entire disc, even if it is recorded in a compatible
format and is playable on other players. To help
avoid playback problems, use the following
guidelines when recording discs:
Open sessions are ignored. Only sessions
that are closed are playable.
For multi-session CDs that contain only
multiple CD-Audio sessions, the player will
renumber the tracks so each track number is
unique.
For CD Data (or CD-ROM) discs, always use
the ISO-9660 (Level 1 or Level 2), Joliet, or
Romeo format. Other formats (such as UDF,
HFS, or others) are not supported.
The player recognizes a maximum of 512 files
and 99 folders per CD-R and CD-RW disc.
Mixed media recordable DVD formats will
only play the Video_TS portion of the disc.
If you are still having trouble writing a disc that
is playable in the Blu-ray™ Disc player, check
with the disc recording software publisher for
more information about burning playable discs.
The recommended method for labeling
recordable discs (CD-R, CD-RW, and DVD-R) is
with a permanent marker. Do not use adhesive
labels as they may separate from the disc,
become stuck, and cause permanent damage
to the DVD player.
