I just installed a DVD drive and I cannot play DVD disks. What is the problem?

$ sudo apt-get install gstreamer0.10-ffmpeg gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse

Ok, I ran the command in the terminal and it still does not work. When I insert a DVD and tell it to open with Movie Player, Movie player opens, but I get an error message on the screen that says: Could not read from resource. What does this mean? When I ran the command in the terminal, this is what came back:

stevenshown@ubuntu:~$ sudo apt-get install gstreamer0.10-ffmpeg gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse

So what does all this mean? What do I have to do to be able to play a simple DVD disk?

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

Thank you actionparsnip, that fixed the problem-but of course it still does not work on Totem Movie player, but I installed VLC media player and it works like a charm. However, I do still have issues when it comes to ripping a copy protected DVD to my hard drive and changing it to a smaller format to use on my portable devices. I tried K9copy, but it caused my processor to hang at 98-100 percent, overheated my system after about 10 minutes, which caused my system to just shut off. I had to wait about 20 minutes for the system to cool down before I could start it back up. Is there any way to get this done without crashing my system? If not, then I may have to look into buying a better cooling system for my processor.

Please create a seperate question for the DVD ripping.

Ok, I solved the problem with DVD ripping. I have to use K9copy, but I solved the problem with the overheating. My processor cooler heat sink was clogged with dust and etc, so I gave the whole system a thorough cleaning, now runs much more efficiently, boots up much quicker, and has yet to crash. Looks as though all is well now, thank you for your assistance in this matter
