•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 notice: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

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.

Using the remote control unit correctly

When you use remote control, point the unit at the appliance you want to control (DVD recorder, TV set or satellite receiver). Ensure that there is no obstacle between the remote control unit and the appliance, otherwise the infrared signal

carrying the remote control commands will be
blocked.To control your DVD recorder, ensure	EN
that the remote control unit is in DVD mode by	EN
pressing once on the DVD key before using any
other keys.

Recording

Your DVD recorder has recording functions similar to a video recorder. It lets you record programmes to a disc in the DVD family DVD (DVD R/RW) or to the internal hard disc (DVR or HDD). For the same disc, the recording time depends on the quality settings that you can adjust according to the time left on the disc.The recording may be immediate or deferred.

NICAM sound

NICAM sound is digital, compatible with analogue tv sets. It is broadcast by certain channels and relayed by certain emmiters in some European countries. NICAM (Near Instantaneously Companded Audio Multiplex) is also used to broadcast Dolby Surround stereophonic programmes or for simultaneous broadcasting in two languages or for two different sounds (intended for blind and poorly sighted people).

Downloading Naviclick data

The downloading of Naviclick data (at 3am or 8am) can be quite long (up to 2 hours). During this time you should not use your DVD recorder, nor turn it on or have a programme programmed for recording during this updating time (from 3am to 5am or 8am to 10am) otherwise the information will be lost. For countries that provide the NexTView service we recommend that you set the downloading time to 3am.The full guide of TV programmes can only be consulted the following day after an initial installation. It is necessary to allow your DVD recorder to download the guide at the time set in the Naviclick Setup.
