playing DVD's on Ubuntu Intrepid Ibex

You still cannot easily play dvd's on free software Linux distributions... sadly...

But those guys describe it nicely how to do it with the medibuntu repository - only for Hardy. For Intrepid, the command must be slightly changed (and I prefer aptitude, as it also keeps a log of what it does)

So, as root, do:

wget -O /etc/apt/sources.list.d/medibuntu.list
aptitude update
aptitude install medibuntu-keyring
aptitude update
aptitude install libdvdcss2 w32codecs
