Recommendations
and
information
concerning
discs
CD-R
and
CD-RW
discs
This player can play most CD-R and CD-RW discs. However, depending on the recorder of the discs
of your personal computer, the type of disc and recording method used, some discs might not play,
or the performance
might not meet the expected standard of quality. When playing a CD-R disc, it is
completely
normal for the unit to take up to 20 seconds to recognize the disc before it plays. If the
disc is not recognized after a period of 20 seconds, remove the disc, and then insert it again• If after
several trials, the disc cannot be recognized, make sure you have followed the recommendations
below or try another type of disc.
• Whatever the actuaI recording capacity of a disc, do not fill it to maximum capacity.
• Use CD-R discs rather than CD-RW(re-recordable
CDs), as replay of CD-RWs may
sometimes not work properly.
• Use a reliable and good quality recording software.
• Before recording on a disc, close all applications on you personal computer in order to
optimize the quality and reliability of recordings on the disc.
CD-R
and
CD-RW
discs
with
mp3
format
"Sound"
files
In the case of discs that include mp3 files, follow not only the general recommendations
for CD-R
and CD-RW discs, but also the following specific recommendations:
The format of your mp3 files should be ISO 9660 or JOLIET• These files are compatible with DOS
and Windows applications
as well as with Mac OS.
Your mp3 files must have a name no longer than 12 characters as well as the suffix ".mp3". They
must be recorded in the form: title.mp3.Ensure
that you do not leave spaces or use special
characters such as (.,/,\,=,+)in
the name.
Do not attempt to record protected mp3 files. Such files are coded and protected.
Use a decompression
transfer rate of at least !28 kb/sec (kilobytes/second)
when recording mp3 files•
Sound quality with mp3 files basically depends on the rate of compression/decompression
you
choose. Getting audio CD quality sound requires and analog/digital
sampling rate, that is conversion
to mp3 format, of at least 128 kb/sec and up to 160 kb/sec. However, choosing higher rates,
like 192 kb/sec or more, only rarely give even better sound quality• Conversely, files with sampling
rates below 128kb/sec will not be played properly•
Important:
The above recommendation
cannot be taken as a guarantee
that the DVD player
will play mp3 recordings,
or as an assurance
of sound quality. You should note that certain
technologies
and methods for mp3 file recording on CD-Rs prevent
optimal playback
of
these files on your DVD player (that is degraded sound quality and even, in some cases,
inability of the player
to read the file or files).
