Additional Information

Compatible Formats

In order to ensure playback, discs must conform EN with DVD, CD, VCD or SVCD standards. This unit

may not play some recordings or files due to differences in recording formats, software used and disc types.

DVD-Video

Digital video discs - 12 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, 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+Rewritable

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 Compact Disc (VCD)

CD on which you can record up to 74 min. of VHS quality video associated with still images, audio tracks and interactive menus.

Super Video Compact Disc (SVCD)

Most SVCDs comply with the IEC62107 standard. SVCDs can be used to record up to 70 minutes of digital sound and images in accordance with MPEG-2 standards for video and MPEG-1 standards for audio.

Audio CDs

Audio CDs (12 cm).

CD-R, CD-RW

Most CD-R (one recording only) and CD-

RW discs (rewritable).

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. When playing a CD-R disc, it is normal for the unit to take up to 20 seconds to recognize

the disc before starting to play.

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

•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. For CD-R mp3 discs, please follow all the recommendations for CD-R, 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.

•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.
