Notes about CDs/DVDs can be found here
(Y page 73). DVD playback conditions
There are video DVDs available on the market
which do not conform to the current stand-
ards.
Such DVDs may have picture, sound or other
playback problems.
The Rear Seat Entertainment System can play
back video DVDs produced according to the
following standards:
R Region code 2 (for Europe) or region code
0 (no region code)
R PAL or NTSC standard
You will generally find the relevant details
either on the DVD itself or on the DVD case.
i If you insert a video DVD with a different
region code, you will see a message to this
effect.
i The Rear Seat Entertainment System is
set to region code 2 at the factory. This
setting can be changed at an authorized
Mercedes-Benz Center. This will allow you
to play video DVDs with a different region
code, provided that they are produced in
accordance with the PAL or NTSC stand-
ard.
Playback problems may occur when play-
ing copied discs. There is a large variety of
discs, DVD authoring software, writing soft-
ware and writers available. This variety
means that there is no guarantee that the
Rear Seat Entertainment System will be
able to play video DVDs that you have cop-
ied yourself. Function restrictions
Depending on the DVD, it is possible that cer-
tain functions or actions will be temporarily
blocked or may not function at all. As soon as 96
