In order to ensure playback, discs must conform
with DVD, CD, VCD or SVCD standards. This unit
may not play some recordings or files due to
differences in recording formats, software used &
Disc types.
DVD-Video
Digital video discs - 12 cm, single or
double sided, single or dual layer. DVDs
are high density optical discs on which
high quality picture and audio are recorded by
means of digital signals.
DVD-R,DVD-RW, DVD+R, DVD+RW
Most DVD-R and DVD+R (one recording
only), DVD-RW and DVD+RW discs
(rewritable), depending on the DVD writer
and discs used. Recordings using DVD-R
and DVD-RW discs must be made in Video
DVD mode. Recordings using DVD+RW discs must
be made in accordance with the specifications for
DVD+RW discs with a 4.7 GB capacity.
VCD - Video Compact Disc
CD on which you can record up to 74 min.
of VHS quality video associated with still
images, audio tracks and interactive
menus.
SVCD - Super Video Compact Disc
Most SVCDs comply with the IEC62107
standard. SVCDs can be used to record up to 70
minutes of digital sound and images in
accordance with MPEG-2 standards for video and
MPEG-1 standards for audio.
Audio CDs
Audio CDs (12 cm).
CD-R, CD-RW
Most CD-R (one recording only) and CD-
RW discs (rewritable).
CD-Rs written during a multisession recording can
be played, provided that the session has ended
before the disc is played (depending on the write
software). However, depending on the
condition of the CD-writer, computer and the disc
used, you may find that not all discs will play.
When playing a CD-R disc, it is normal for the
unit to take up to 20 seconds to recognize
the disc before starting to play.
If the disc is not recognized after a period of 20
seconds, remove the disc, and insert it again.
• Do not use its full capacity.
• CD-Rs should be preferably used instead of CD-
RWs (rewritable CDs) as, in certain cases, CD-
RW playback may be faulty.
• Use reliable, good-quality CD write software.
• Close all other applications on the computer to
ensure reliable CD-R disc recording.
Mp3 files
CD-R and CD-RW discs containing audio
files in mp3 format. For CD-R mp3 discs,
please follow all the recommendations for CD-R,
along with the comments below:
• Your mp3 files should be ISO 9660 or JOLIET
format. ISO 9660 format and Joliet mp3 files
are compatible with Microsoft’s DOS and
Windows, as well as with Apple Mac.
• Mp3 filenames should not exceed 8 characters,
and should end with the “.mp3” extension.
General name format: Title.mp3. When
composing your title, use 10 characters or less,
no spaces, and avoid the use of special
characters including (. , / , \ , = ,+).
• The total number of files on a disc should be
less than 400.
• Use a decompression transfer rate of at least
128 kB/sec (kilobytes/second) when recording
mp3 files. Sound quality with mp3 files
basically depends on the rate of compression/
decompression you choose. Obtaining audio
CD quality sound requires an analog/digital
sampling rate, that is conversion to mp3
format, of at least 128 kB/sec and up to 160
kB/sec. Choosing higher rates, such as 192
kB/sec or more, only rarely produces even
better sound quality. Conversely, files with
sampling rates below 128 kB/sec will not play
properly.
