Further information
• 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
that the remote control unit is in DVD mode by
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.
