DISC YOU CAN PLAY

While advances have been made to ensure that your disc player is compatible with the largest number of discs possible, however it cannot be guaranteed that you will be able to play discs which might not be compliant with audio CD standards. In the case of writable and rewritable discs, compatibility with this player depends on the CD/DVD writer, the right software and the disc used.

DVD-Video

Digital video discs - 12 cm and 8 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

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.

Video CD(VCD)

VCD stands for Video Compact Disc which contains video footage, still images, audio tracks and interac- tive menus.

Audio CDs

Audio CDs (8 and 12 cm).

CD+G

CD+G is a Karaoke music format. The song words will be displayed on the TV screen and change color when it is time to sing the lyrics. There are no video scenes (movies) in the background.

CD-R & CD-RW

Most CD-R (one recording only) and CD-RW discs (rewritable). This player can play most CD-R discs. CD-Rs written during a multi-session recording can also 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 successfully. When playing a CD-R disc, it is completely normal for the unit to take up to 20 seconds to recognize the disc before start- ing to play. If the disc is not recognized after a period of 20 seconds, remove the disc, and then insert it again.

•Irrespective of the actual recording capacity of the CD-R, 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. As for CD-R MP3 discs, please follow all the recommendations for CD-R above, 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. These two formats are the most widely used.

•MP3 filenames should not exceed 12 characters, and should end with the “.MP3” extension. General name format: “Title.MP3”. When composing your title ensure 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 128kB/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 converted to MP3 format, of at least 128kB/sec and up to 160kB/sec. Choosing higher rates, such as 192 kB/sec or more, will rarely produce better sound quality. Conversely, files with sampling rates below 128kB/sec will not play properly.

•Do not try recording copyright-protected MP3 files. “Secured” files are encrypted and code- protected to prevent illegal copying. You must not copy such files.

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 (i.e. degraded sound quality and even, in some cases, inability of the player to read the file).

WMA Files

CD-R with WMA files. Usable format similar to MP3 files; also see “MP3 Files” for reference.

JPEG Files

CD-R and CD-RW with JPEG files. Certain JPEG files, including progressive JPEG files, cannot be read by this player.
