About MP3/WMA/JPEG discs
Playable MP3/WMA/JPEG discs and files

• Discs recorded in the ISO 9660 format are play-

able (except discs recorded in the "packet write" 

format (UDF format)).

• Discs recorded in the multi-session format are 

also playable.

• Files with an extension of ".mp3", ".wma", ".jpg" 

or ".jpeg" (extensions with uppercase and lower-

case letters mixed are also acceptable) are play-

able.

• 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 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, an 

off-the-shelf MP3/WMA disc may be played back 

in an order different from that indicated 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.

• This product cannot play back animations such 

as MOTION JPEG, or still pictures (TIFF etc.) 

other than JPEG, and image data with sound.

• The resolution of 640 x 480 pixels is recom-

mended for JPEG files. If a file has been 

recorded at a resolution of more than 640 x 480 

pixels, display may take a long time. An image 

with a resolution of more than 8192 x 7680 pix-

els cannot be displayed.

• Files recorded on DVD-R/RW discs cannot be 

played back.

DVD VIDEO
A DVD VIDEO consists of "titles" and each title 
may be divided into "chapters".

DVD AUDIO
A DVD AUDIO consists of "groups" and each 
group may be divided into "tracks".
Some discs include a "bonus group" that requires 
a password for playing (

page 31).

VCD/SVCD/CD
VCD, SVCD and CD consist of "tracks".
In general, each track has its own track number. 
(On some discs, each track may also be further 
divided by indexes.)

MP3/WMA [JPEG] discs
On an MP3/WMA [JPEG] disc, each still picture 
(material) is recorded as a track [file]. Tracks 
[Files] are usually grouped into a folder. Folders 
can also include other folders, creating hierarchical 
folder layers. 
This unit simplifies the hierarchical construction of 
a disc and manages folders by "groups".

This product can recognize up to 1000 tracks [files] 
in a disc. Also, the product can recognize up to 
150 tracks [files] per group and up to 99 groups in 
a disc. Since the unit ignores the tracks [files] 
whose numbers are exceeding 150 and the groups 
whose numbers are exceeding 99, they cannot be 
played back.

• If there is any type of files other than MP3/WMA 

[JPEG] files in a disc, those tracks [files] are also 
counted in the total file number.
