Notes on MP3/WMA Recordings
About MP3
•
An MP3 file is audio data compressed by
using the MPEG1 audio layer-3 file-coding
scheme. We call files that have the “.mp3” file
extension “MP3 files”.
•
The VCR/DVD Recorder can not read an MP3
file that has a file extension other than “.mp3”.
About WMA (Window Media Audio)
•
A WMA file is made using Microsoft audio
compression technology.
•
WMA (Windows Media Audio) offers double
the audio compression of the MP3 format.
MP3 / WMA disc compatibility with this play-
er is limited as follows:
•
The player cannot read an MP3/WMA file that
has a file extension other than “.mp3” /
“.wma”.
•
CD-R physical format should be ISO 9660
•
If you record MP3 / WMA files using software
that cannot create a file system (eg. Direct-
CD) it is impossible to playback MP3 / WMA
files. We recommend that you use Easy-CD
Creator, which creates an ISO 9660 file sys-
tem.
•
The total number of files and folders on the
disc are free but the total number of files and
folders on the folder should be less than 999.
This VCR/DVD Recorder requires discs and record-
ings to meet certain technical standards in order to
achieve optimal playback quality. Pre-recorded
DVDs are automatically set to these standards.
There are many different types of recordable disc
formats (including CD-R containing MP3 or WMA
files) and these require certain pre-existing condi-
tions (see above) to ensure compatible playback.
Customers should note that permission is
required in order to download MP3 / WMA files
and music from the Internet. Our company has
no right to grant such permission. Permission
should always be sought from the copyright
owner.
Notes on MP3/WMA Recordings
• Depending upon the size and number of JPEG
files, it could take a long time for the DVD+VCR
to read the disc’s contents. If you don’t see an on-
screen display after several minutes, some of the
files may be too large — reduce the resolution of
the JPEG files to less than
5760 x 3840 pixels
and burn another disc.
• The total number of files and folders on the disc
should be less than
1500
.
• Some discs may be incompatible due to a differ-
ent recording format or the condition of disc.
• Ensure that all the selected files have the “.jpg”
extensions when copying into the CD layout.
• If the files have “.jpe” or “.jpeg” extensions, please
rename them as “.jpg” file.
• File names without “.jpg” extension will not be
able to be read by this DVD+VCR. Even though
the files are shown as JPEG image files in
Windows Explorer.
DivX disc compatibility with this player is limited
as follows:
• Available resolution size of the DivX file is under
720x576 (W x H) pixel.
• The file name of the DivX subtitle is limited to
characters.
• If there is impossible code to express in the DivX
file, it may be displayed as " _ " mark on the dis-
play.
• If the number of the screen frame is over 30
frames per second, this unit may not operate
normally.
• If the video and audio structure of recorded
file is not interleaved, either video or audio is
outputted.
• If the file is recorded with GMC, the unit sup-
ports only 1-point of the record level.
* GMC?
GMC is the acronym for Global Motion Compensation. It
is an encoding tool specified in MPEG4 standard. Some
MPEG4 encoders, like DivX or Xvid, have this option.
There are different levels of GMC encoding, usually
called 1-point, 2-point, or 3-point GMC.
