DVD playback

I bought an external DVD RW today. (Samsung SE-208DB/TSBS Black)

I had to install libdvdcss to be able to playback a regular DVD Video.

And still have to use -vo gl2 to get the picture right.

Get libdvdcss
Last version of libdvdcss is 1.2.13.
Our Debian/Ubuntu repository can be accessed by adding the following content to /etc/apt/sources.list
deb http://download.videolan.org/pub/debian/stable/ /
deb-src http://download.videolan.org/pub/debian/stable/ /
And by running
wget -O - http://download.videolan.org/pub/debian/videolan-apt.asc|sudo apt-key add -
libdvdcss is available through Git or by browsing the releases.

Go to Synaptic and browse libraries (without "verse") for libdvdcss.

To play it with Mplayer:

For the complete list of available options, please read the man page. The syntax to play a standard DVD is as follows:
mplayer dvd:// [-dvd-device ]
Example:
mplayer dvd://1 -dvd-device /dev/hdc

my command line looked like this:
 ~$ mplayer dvd://1 -dvd-device /media/DVDMEDIA/ -vo gl2
