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.

If the disc is not recognized after a period of 20 seconds, remove the disc, and insert it again.

• 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.

• Do not record copyright-protected mp3

files. “Securized” files are encrypted and

codeprotected to prevent illegal copying.

Important: The above recommendations does not guarantee that the DVD player will play mp3 recordings, or as an assurance of sound quality. Certain technologies and methods for mp3 file recording on CD-Rs prevent optimal playback of these files on your DVD player (i.e. degraded sound quality and in some cases, inability of the player to read the file).
