DVD Playback Capability On Ubuntu Karmic Koala (9.10)

On the DVD encryption is already in, usually we'll hassle to play the dvd, because there is not yet installed packages are: libdvdcss2. if you want to play DVDs that have the encryption you have to install it by downloading the package, follow these steps:

Go to terminal and type :

$ wget -c http://packages.medibuntu.org/pool/free/libd/libdvdcss/libdvdcss2_1.2.10-0.2medibuntu1_i386.deb

Login as root to install libdvdcss2 by type :

$ sudo su

$ dpkg -i libdvdcss2_1.2.10-0.2medibuntu1_i386.deb

Or you can add medibuntu repository on your system by type :

$ wget http://www.medibuntu.org/sources.list.d/karmic.list --output-document=/etc/apt/sources.list.d/medibuntu.list
$ apt-get update
$ apt-get install medibuntu-keyring
$ apt-get update
$ apt-get install libdvdcss2 

Instead of downloading directly from Medibuntu, you could also use the script included with the libdvdread4 package to download and install libdvdcss2:

$ apt-get install libdvdread4
$ /usr/share/doc/libdvdread4/install-css.sh

And if you have not already install ubuntu-restricted-extras, you can also install w32codecs by type :

$ apt-get install w32codecs

Happy Testing...!!
