Further information

for television screens do not allow a higher quality given their limited characteristics. In this case ensure that you reduce the quality of your photographs before recording on a disc in order not to impede the proper running of your player.This is because excessively loaded pictures would slow down or might prevent the proper functioning of the slide show during playback on your player. Compatibility of JPEG files depends on the software on which they were created and on the size of files expressed in pixels. Some JPEG files, including Progressive JPEG files (display in stages) cannot be played on this appliance.

Audio files and CD-R / CD-RW discs

In the case of discs that include mp3 files, follow not only the general recommendations for CD-R EN and CD-RW discs, but also the following specific recommendations:

•The format of your mp3 files must be ISO 9660 or JOLIET. These files are compatible with DOS and Windows applications, as well as with Mac OS.

•Your mp3 files must have a name no longer than 12 characters as well as the suffix “.mp3”. They must be recorded in the form: title.mp3. Ensure that you do not leave spaces or use special characters such as ( . , / , \ , = ,+) in the name..

•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.To obtain sound quality equivalent to that of an audio CD, use files for which the sampling rate during conversion from analogue audio to mp3 format is between 128 kbps and 160 kbps. Higher compression rates, such as 192 kbps or more, will only rarely improve sound quality. Conversely, files with sampling rates below 128 kb/sec will not be played properly.

•Do not attempt to record protected mp3 files. Such files are coded and protected.

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 (that is degraded sound quality and even, in some cases, inability of the player to read the file or files).

DivX files and CD-R / CD-RW discs

DivX is a compression format answering the MPEG-4 standard and that allows an entire film to be contained on a single CD.

The compatibility of DivX formats depends on MPEG-4 coding software, disc design software and the recording software employed, as well as the discs themselves.

What codecs can your player read?

•Playback of DivX 3.11 content • Playback of DivX 4 files (MPEG-4 simple profile) • Playback of DivX 5 files (MPEG-4 simple profile and additional functions such as bi-directional frames. Qpel and GMC are not supported) • Resolutions up to 720 x 480 at 30fps and 720 x 576 at 25fps are supported • Macroblocks per second 40500 • Maximum average bitrate 4000 kbps • Maximum peak bitrate during any 3 seconds of video 10000 kbps • Minimum VBV buffer size (kbytes) 384k bytes

Note: for DivX 3.11 content at Home Theater Profile, the required average bitrate is 1000 kbps, and the required maximum peak bitrate is 4000 kbps. Mpeg4 and Xvid content may or may not play back depending on the exact recording method and codec used.
