About MP3/WMA/JPEG/ASF/DivX discs

able (except CDs recorded in the "packet write"
format (UDF format)).

also playable.
• Files with an extension of ".mp3", ".wma", ".jpg",
".jpeg", ".asf", ".divx", ".div" or ".avi" (extensions
with uppercase and lowercase letters mixed are
also acceptable) are playable.
• This product cannot play back DVDs recorded in
multi-session or multi-border format.
Notes on MP3/WMA/JPEG/ASF discs and files
• A disc may not be played back, or reading it may
take a long time depending on its recording con-
ditions or properties.
• The time needed for reading varies with the num-
ber of groups or tracks (files) recorded on the disc.
• If a character other than single byte English
characters is used in the file name of an MP3/
WMA/JPEG/ASF file, the track/file name will not
be displayed correctly.
• The order of tracks/groups displayed on the
MP3/WMA Control screen, and the order of files/
groups displayed on the JPEG Control screen
may be different from that of files/folders dis-
played on PC's monitor screen.
• In the case of MP3/WMA discs, since groups/
tracks are played back in alphabetical order, a
commercially available MP3/WMA disc may be
played back in an order different from that indi-
cated on the label attached to the disc.
• Playing back an MP3/WMA file including a still
image may take a long time. The elapsed time is
not displayed until playing back starts. If playing
back starts, the elapsed time may not be dis-
played correctly.
• For an MP3/WMA file, a disc with a sampling fre-
quency of 44.1 kHz and transmission rate of 128
kbps is recommended.
• This product is not compatible with MP3i or
MP3PRO.
• This product can play back a baseline JPEG file,
excluding monochromatic JPEG files.
• This product can play back JPEG data taken with a
digital camera conforming to the DCF (Design
Rule for Camera File System) standard (when a
function is applied such as the automatic rotation
function of a digital camera, data goes beyond the
DCF standard, so the image may not be dis-
played).
• If data has been processed, edited and restored
with PC image editing software, the data may
not be displayed.

els cannot be displayed.
