Further information

To view your JPEG images on a TV set you do not need to record your photographs with a
resolution above 400,000 pixels (which corresponds to an image format of about 720 x 576 dots),
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	E N
the size of files expressed in pixels. Some JPEG files, including Progressive JPEG files (display in	E N
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
and CD-RW discs, but also the following specific recommendations:

•The format of your mp3 files should 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. Getting audio CD quality sound requires an analogue/digital sampling rate, that is conversion to mp3 format, of at least 128 kb/sec and up to 160 kb/sec. However, choosing higher rates, like 192 kb/sec or more, only rarely give even better 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 Content (Based on MPEG-4 Simple Profile) • Playback of DivX 5 Content (MPEG-4 simple profile plus additional features 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.
