MP3/WMA Playback

CD-R MP3/WMA discs

When playing CD-R MP3 or WMA discs, please follow these recommendations :
• Your MP3 or WMA files should be ISO 9660 or JOLIET format.
ISO 9660 format and Joliet MP3 or WMA files are compatible with Microsoft DOS and Windows,
and with Apple Mac. These two formats are the most widely used.
• When naming your MP3 or WMA files, do not exceed 8 characters, and use “.mp3” and
“.wma” as the file extensions.
Use the general name format of “Title.mp3” or “Title.wma”. When composing your title, make sure
you use 8 characters or less, have no spaces in the name, and avoid the use of special
characters (.,/,\,=,+).
• Use a decompression transfer rate of at least 128 Kbps when recording MP3 files.
The sound quality of MP3 files depends on the rate of compression/decompression. To
approximate CD quality audio, you will need an analog/digital sampling rate of at least 128 Kbps
and up to 160 Kbps. Higher rates (192 Kbps or more) only occasionally yield better sound quality.
Conversely, rates below 128 Kbps will yield inadequate results.
•Use a decompression transfer rate of at least 64Kbps when recording WMA files.
The sound quality of WMA files depends on the rate of compression/decompression. To
approximate CD quality audio, you will need an analog/digital sampling rate of at least 64 Kbps
and up to 192 Kbps. Rates below 64Kbps or above 192 Kbps will yield inadequate results.
• Do not try recording copyright-protected MP3 files.
Certain "securized" files are encrypted and code-protected to prevent illegal copying, including
Windows MediaTM (registered trademark of Microsoft, Inc.) and SDMITM (registered trademark of
The SDMI Foundation). You cannot copy such files.
• Important: The above recommendations cannot be taken as a guarantee that the DVD player will
play all 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).
• This unit can play a maximum of 500 files and 300 folders per disc.
