ARCH LINUX: How-to watch DVD movies

By default, you won't be able to play DVD movies in Arch Linux, but that can be solved really easy.

Step 1:
Add your user to the group 'optical'. This can be done with the command:
# gpasswd -a USERNAME optical

Or by adding your username to the end of the 'optical' line in the file /etc/group

Step 2:
Install the necessary DVD libraries from Pacman.

# pacman -Sy libdvdread libdvdnav libdvdcss

Step 3:
Select a DVD player. I use VLC, because it's very simple to use but extremely powerful.

You can search in the Arch Linux's repository for the DVD player of your liking, and then install it by:

# pacman -Sy NAMEOFPLAYER

Step 4:
Now log out and in again for the actions to take place, and now you should be able to play DVD's in Arch Linux!
