Have installed the libraries suggested for getting encrypted DVD's to play but its still not happening. When I typed in
sudo apt-get install ubuntu-restricted-extras
sudo /usr/share/doc/libdvdread4/install-css.sh
the following replied

ubuntu-restricted-extras is already the newest version.
The following packages were automatically installed and are no longer required:

Use 'apt-get autoremove' to remove them.
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
I try to remove and get
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
How do I reply to this and should I be removing these files anyway (ie could they be stopping the DVD's from working?)
