CD-R MP3 disc requirements

When playing CD-R MP3 discs, please follow the recommendations 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, and with Apple's
Mac. These two formats are the most widely used.
• When naming your MP3 files do not exceed 8 characters, and place ".mp3" as the file extension.
General name format of: Title.mp3. When composing your title, make sure that you use 8 characters or
less, have no spaces in the name, and avoid the use of special characters including: (.,/,\,=,+).
• 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.
Getting audio CD quality sound requires an analog/digital sampling rate (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 better sound quality.
Conversely, files with sampling rates below 128 kb/sec will not be played properly.
• Do not try recording copyright protected MP3 files.
Certain "securized" files are encrypted and code protected to prevent illegal copying. These files are of the
following types: Windows MediaTM (registered trade mark of Microsoft Inc) and SDMITM (registered trade
mark of The SDMI Foundation). You cannot copy such files.
•Your DVD player only accepts one level of file directory.
Consequently you must choose:
-either to save all your MP3 recording files at the root of the disc;
-and/or create folders in the directory for each artist or music type (e.g.classical, rock, jazz, etc)
• Important: The above recommendations 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 (degraded sound quality and in some cases, inability of the
player to read the files).
