Notes about Audio DVD Discs
COMAND can playback commercially
available, prerecorded audio DVDs that bear
the following label. You will usually find the
label on the DVD booklet, the inlay or the DVD
itself.
i Audio DVDs differ from recordable DVD-R
and DVD-RW discs.
Data on audio DVDs are stored either in
uncompressed format or in lossless
compressed format. The sound quality on
audio DVDs is therefore better than on
recordable DVDs that contain MP3 data
because the MP3 format uses a lossy type of
compression. You cannot delete data from or
record additional data to commercially
available, prerecorded audio DVDs. Please
note the following information about CDs/
DVDs and pay special attention to the notes
on copied and/or selfwritten CDs/DVDs.
Permissible Bit and Scan Rates
Fixed and variable bit rates from 32 kbps to
R
320 kbps
Scan rates from 8 kHz to 48 kHz
R
i Only use MP3 tracks with a bit rate of
128 kbps or higher and with a scan rate of
CD Audio/DVD Audio/MP3
44.1 kHz or higher. Lower rates may result
in impaired sound quality. This is
particularly true if the surround sound
function has been activated.
®
WMA (Windows Media Audio) format of the
following type:
fixed bit rates from 5 kBit/s up to
R
384 kBit/s
sampling rates from 8 kHz to 48 kHz.
R
COMAND does not support WMA files of the
following type:
DRM (Digital Rights Management)
R
encrypted files
i If other music files are stored in these
audio formats on a storage medium, in
addition to MP3 files, the loading process
may take longer before the first track is
played.
Notes about CD/DVD Discs
i Discs with copy protection do not comply
with the CD audio standard and in some
cases cannot be played by COMAND. When
playing copied discs, problems may occur
with the playback.
A wide variety of discs, disc writing software
and writers are available. Due to this variety
we cannot guarantee that the system will be
able to play discs that you have written/
copied yourself.
There may be playback problems with
userburned CDs with a storage capacity of
more than 700 MB. These CDs do not meet
current valid standards.
i
When playing a DVD audio, it may be the
case with numerous albums that the last
track does not contain any music and
COMAND switches to the next track. This
is due to the production method and does
not imply a fault with the unit.
