On playing DVD's in Ubuntu

I'm a geek. Therefore, the command line does not scare. Bash is my friend, and I like PowerShell most for bringing me the ability to do very real work from a Windows shell script.

However, having recently converted my primary desktop to Ubuntu, every so often I really would like to use or view a DVD. But I can't, by default, in Ubuntu 12.10, view a movie.

So, after some quick searching, I found that to watch a movie in Movie Player in Ubuntu required me to install the package Ubuntu-restricted-extras. This was followed by a quick call on the command line to

sudo /usr/share/doc/libdvdread4/install-css.sh
