Watching a DVD in Xubuntu 9.04

After the previous reinstall two months ago, DVDs stopped working.

Here's how I got it to work:

1. Add the medibuntu repository, if you haven't already
   

   sudo cp /etc/apt/sources.list /etc/apt/sources.list~   # Backup the sources.list file
   sudo mousepad /etc/apt/sources.list &                  # Open the sources.list file in an editing window
   
     ## In sources.list, append the following two lines at the bottom, then save (don't close it)
     ## Medibuntu
     deb http://packages.medibuntu.org/ jaunty free non-free
     ## If you use debtorrent, use: deb debtorrent://localhost:9988/packages.medibuntu.org/ jaunty free non-free
   
   sudo apt-get update
   sudo sudo apt-get install medibuntu-keyring
   sudo apt-get update
   

2. Use these two terminal commands to add the correct software (source):
   

   sudo apt-get install totem-xine libxine1-ffmpeg libdvdread4
   sudo /usr/share/doc/libdvdread4/install-css.sh
   # Note - this installs the libdvdcss2 package, which is *not* in the repositories.
   # If you use this list of packages to rebuild your system, for example by using a 
   # Jablicator metapackage, it will fail due to this missing dependency.
   

3. I installed ubuntu-restricted-extras for unrelated reasons. So I don't *think* it's necessary.
   

   sudo apt-get install ubuntu-restricted-extras
   

4. Finally, I got an error message when I put in a dvd:
   "Could not open location; you might not have permission to open the file." This is indeed a permission issue. Fix it with:
   

   sudo chmod 755 /media/cdrom0

   And then try opening the DVD from within your player application (Totem).
