I am sorry if this has already been posted, but I haven't found an answer to my problem yet.
I have recently installed Ubuntu 12.04 on my girlfriends notebook and she now complains that her DVDs won't play in VLC or any other video player.
Whenever I try to insert a DVD and open it up with VLC player, it just crashes without any error message or similar. Also MPlayer and SMplayer don't work.
I might add that certain other DVDs do play. The movies we are talking about in specific are
So Undercover, region code 2, does not work
some twilight movie, region code 2, also does not work
however, tv series like Gossip Girl, region code 2 as well, do work.
Now I have of course done my reserach on this topic and found out that
1. either libdvdcss2 is not installed --> it is, I checked and I have tried it with different sources (from the "regular" Ubuntu repository, the medibuntu repo and some others)
2. libdvdread4 or similar are not installed --> also they are installed
3. sudo /usr/share/doc/libdvdread4/install-css.sh was missing --> I've done that too
4. the region code of the DVD might be wrong --> the DVDs have region code 2, whereas the computer is from Canada (which is in the code 1 region). I have also used regionset to set the code of the DVD drive to 2 but it somehow still doesn't play.
I have no idea what could be the cause of this problem but I would be really thankful for any help.
Thanks for your effort in advance,
