on the TV screen, but any
operation cannot be performed.
A disc cannot be played.
Not JPEG files but MP3 files are
played.
POSSIBLE CAUSE
No MP3 files are recorded on the disc.
MP3 files do not have the correct file
extension in their file names.
MP3 files are not recorded in the format
compliant with ISO 9660 Level 1 or 2.
MP3 files are made at the bit rate of less
than 64 kbps.
The MP3/JPEG setting is set to “JPEG.”
Any MP3 files or JPEG files are not
recorded on the disc, or the disc is the
unplayable disc (such as CD-ROM).
No JPEG files are recorded on the disc.
JPEG files do not have the correct file
extension in their file names.
JPEG files are not recorded in the format
compliant with ISO 9660 Level 1 or 2.
The MP3/JPEG setting is set to “MP3.”
SOLUTION
Replace the disc.
Add the file extension—.mp3, .Mp3,
.mP3, or .MP3—as their file names. (See
page 46.)
Replace the disc. (Record MP3 files
using a compliant application.)
This system cannot playback such discs.
Replace the disc.
When both MP3 files and JPEG files are
recorded on a disc, to play MP3 files, set
the setting to “MP3.” (See page 53.)
Replace the disc. (See page 5.)
Replace the disc.
Add the file extension—.jpg, .jpeg, .JPG,
.JPEG or any uppercase and lowercase
combination (such as “.Jpg”)—as their
file names. (See page 48.)
Replace the disc. (Record JPEG files
using a compliant application.)
When both MP3 files and JPEG files are
recorded on a disc, set the setting to
“JPEG.” (See page 53).

Glossary
Aspect ratio
The ratio of vertical and horizontal sizes of a displayed
image. The horizontal vs. vertical ratio of conventional TVs is
4:3, and that of wide-screen TVs is 16:9.
Chapter
See “Titles and chapters.”
Component video signal
A video signal system where parts of information necessary
for reproducing image signal comprised of the three primary
colors of light are transmitted via separate signal lines. Types
of signal, such as R/G/B, Y/P
B/PR, etc., are available.
Composite video signal
Refers to video signal comprised of three kinds of signals
combined: an image signal made up of luminance and
chrominance signals using the frequency multiplication
technique; burst signal providing the basis for color
reproduction; and synchronization signal.
Disc menu
A screen display prepared for allowing selection of images,
sounds, subtitles, multiangles, etc. recorded on a DVD.
Interlaced scanning
In the conventional video system, a picture is shown
on the display monitor in two halves. The Interlaced
scanning system places lines of the second half of the
picture in-between lines of the first half of the picture.
JPEG
A still-picture data compression system proposed by the
Joint Photographic Expert Group, which features little
deterioration in image quality in spite of its high compression
ratio.
Letter box
A method of displaying wide images like movies on a 4:3 TV
screen with no part of the image deleted, by placing black
bands on the top and bottom of the screen. This name has
derived from the screen form looking literally like a letter box.
Linear PCM (PCM: Pulse Code Modulation)
A system for converting analog sound signal to digital signal
for later processing, with no data compression used in
conversion.
MP3
A file format with a sound data compression system. “MP3” is
the abbreviation of Motion Picture Experts Group 1
(or MPEG-1) Audio Layer 3. By using MP3 format, one CD-R
or CD-RW can contain about 10 times as much data volume
as a regular CD can.
Multi-angle
By recording multiple scenes progressing at the same time in
a single title, the user can select view angles. This feature is
called the multi angle function.
Multi-channel
Software having 3 or more channels. Most DVD have more
than 5 audio channels. Reproducing such software using
multiple speakers creates a realistic sound field like a theater.
Multi-language
DVD can have multiple subtitle (up to 32) and audio (up to 8)
languages.
Parental lock
A feature of this system to automatically determine whether or
not to reproduce particular DVD software by comparing its
parental level (a measure of undesirability of scenes, etc.
from educational viewpoint) set for the software beforehand
with that set on this system by the user; if the software’s level
is less restrictive than the user-set level, it will be reproduced.
Playback control (PBC)
Refers to the signal recorded on video CDs or SVCDs for
controlling reproduction. By using menu screens recorded on
a Video CD  or SVCD that supports PBC, you can enjoy
interactive-type software as well as software having a search
function.
Progressive scanning
Progressive scanning displays all the horizontal lines of a
picture at one time, as a single frame. This system can
convert the interlaced video from DVD into progressive
format for connection to a progressive display. It dramatically
increases the vertical resolution.
Region code
A system for allowing discs to be played back only in the
regions designated beforehand. All the countries in the world
are divided into six regions, each region being identified by a
specified region code (or region number). If the region code
given to a disc includes a numeral which matches one in the
region code of a player, the player can play back the disc.
Sampling frequency
Frequency of sampling data when analog data is converted
to digital data. Sampling frequency numerically represents
how many times the original analog signal is sampled per
second.
Surround
A system for creating three-dimensional sound fields full of
realism by arranging multiple speakers around the listener.
S-video signal
Video signal separated into a Y (luminance) signal and a C
(chrominance) signal. This separation of the video results
higher resolution and better quality.
Titles and chapters
A DVD is divided into several titles (large divisions), and each
title is divided into chapters (small divisions).
These divisions are assigned their particular numbers, so that
they are easily accessed.
Transfer rate
The rate of transferring digital data. Usually the measure is in
baud per second. The DVD system applies a variable
transfer rate system for high efficiency.
