DVD will not play

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

May help. You should also add the medibuntu ppa:

sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list && sudo apt-get --quiet update && sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring && sudo apt-get --quiet update

First Item seamed to load but not the second Item

I have been able to burn a DVD from a File on a pen drive and to play it back.

Copy the whole command as ONE and paste to terminal. Don't break up the command. It will fly

Thanks very much, sorry I did it wrong.

Q 1 /What can I do with this new program?

Q 2/ Will the second part do auto updates?

Thanks very much for all your help. DVD "Hurt Locker" played fine.
