Olivier: gxine will not play a DVD - I have done everything else...

what was the output of

sudo /usr/share/doc/libdvdread3/install-css.sh

??

did you have any error ?

Oliver is correct. Try repeating the steps in the how-to guide, just in case you made a mistake.

I advise you to use another method : we will add an extra repository containing codec and extra programs.

enter the following commands in a terminal

sudo gedit /etc/apt/sources.list

and add this line at the end of the file

deb http://fr.packages.medibuntu.org/ gutsy free non-free

save and close.

now enter in the terminal

wget -q http://fr.packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add -

the repository is now added and the key to verify the integrity of the packages has been also added.

enter the following commands (this will install the library needed to decrypt DVD that can be found on the added repository)

sudo apt-get update
sudo apt-get install libdvdcss2

that should work

If that still fails, try to install vlc and read your dvd with it

sudo /usr/share/doc/libdvdread3/install-css.sh

Trying to play a DVD results in an error dialog box that says:
The xine engine failed to start.
No demuxer found - stream format not recognised.

also enter in the terminal

sudo apt-get install w32codecs ubuntu-restricted-extra

(if you are using ubuntu 64bits w64codecs)

this will install additional codecs that may be needed

this seems to be a codec error. doing as advised in my previous post should do the trick

going to bed - will look for more info in the morning.

here is that result...

tadiv@tadiv-desktop:~$ sudo apt-get install w32codecs ubuntu-restricted-extra

vlc plays DVDs, but gxine does not...

Thanks! That did it.

Thanks Olivier, that solved my question.
