I need to watch a DVD for school, but when I try to watch it in VLC, I get this error:

Playback failure:
VLC cannot set the DVD's title. It possibly cannot decrypt the entire disc.
Playback failure:
VLC cannot set the DVD's title. It possibly cannot decrypt the entire disc.
Your input can't be opened:
VLC is unable to open the MRL 'dvd:///media/curticegough/PHYSICAL_DVD_3/VIDEO_TS/'. Check the log for details.

If I open it in nautiuls, I get this error:

This location could not be displayed

Sorry, could not display all the contents of “PHYSICAL_DVD_3”: Error 
when getting information for file 
'/media/curticegough/PHYSICAL_DVD_3/VIDEO_TS.IFO': Input/output error

I already know about DRM and what it is, but I don't know how to get around it.

I also already have all of the usual codecs, including libdvdnav4, libdvdread4, gstreamer1.0-plugins-bad, gstreamer1.0-plugins-ugly, dvdcss2, ubuntu-restricted-extras and libdvd-pkg.

I also have regionset installed just in case I need to use it for some reason.

How do I play my DVD???

  • Have you tries Ubuntu's video player? – George Udosen Jun 12 '17 at 19:54

    @George Yes I have. But that shouldn't matter. VLC should do just as much as Ubuntu's player would and more. – Curtice Gough Jun 12 '17 at 20:11
  • Are you sure the DVD isn't damaged or corrupted? Does it play okay in another player? – Carl H Jun 12 '17 at 20:24
  • *CarlH Yes. The disk is fine. It works perfectly in my Panasonic Blu-ray player, and in MacOS and Windows. – Curtice Gough Jun 12 '17 at 20:46
  • Perhaps VLC is the issue – George Udosen Jun 12 '17 at 20:54
  • @George there is nothing wrong with VLC. If it were just a problem with the player then it should work in Videos and open in Nautilus. It doesn't work in anything. Ubuntu cannot decrypt the disc. – Curtice Gough Jun 13 '17 at 12:31

    Did you sudo dpkg-reconfigure libdvd-pkg after installing the package? – Jorge Castro Jun 13 '17 at 16:16
  • @JorgeCastro Yes. – Curtice Gough Jun 13 '17 at 17:38
  • Does playing other DVDs work? – Robie Basak Jun 21 '17 at 12:19

    @RobieBasak some work, but most of them give the same error. – Curtice Gough Jun 21 '17 at 13:26
  • You mentioned that the disc works fine in MacOS and Windows. Is this on the same hardware as you are using when Ubuntu fails? If not, is it possible that the hardware on which you're running Ubuntu is not capable of reading some category of discs - perhaps more marginal quality ones? To eliminate this, can you check to see if the failing disc works on Ubuntu on some other machine using the live image? – Robie Basak Jun 21 '17 at 21:01
  • @RobieBasak I used to dual-boot Windows and Ubuntu on the same laptop. It is not a problem with the hardware. – Curtice Gough Jun 22 '17 at 01:10

    Can you describe how you have eliminated the possibility of a hardware problem? – Robie Basak Jun 22 '17 at 22:31
  • @RobieBasak It used to work fine on the same laptop under windows, and other DVD's work just fine. It is not a problem with the disk however, because it plays normally in my blu-ray player for the TV and on my iMac. The error I recieved said that Ubuntu couldn't decrypt the disk. – Curtice Gough Jun 23 '17 at 16:45
  • Was the installation of libdvdcss via libdvd-pkg successful? Did you go through the Troubleshooting section of the DVD Playback page? – David Foerster Jun 23 '17 at 22:49
  • @DavidFoerster yes the installation was successful and I did go through the troubleshooting section on the wiki. – Curtice Gough Jun 24 '17 at 11:16
  • Could you do some basic libdvdcss debugging for starters as described here - https://ubuntuforums.org/showthread.php?t=1440147&p=9037249&viewfull=1#post9037249 Then paste the log on https://paste.ubuntu.com/ & post a link so I can look at. Follow instructions completely, i.e. insert disc, close out any pop up or player, delete the .dvdcss folder & THEN run commands. Irregardless of which command you use to open vlc you must use the exports first (post may not be clear on that.. – doug Jun 26 '17 at 02:27
  • Is your disc a Dual-Layer disc? Some players will refuse to play these (like the one in my old laptop). Note that dual-layer isn't the same as double-sided. –  Jun 26 '17 at 10:37
  • Does this answer your question? How can I play encrypted DVD movies? – karel Feb 15 '24 at 01:21

As already someone told you in the comments, you apparently did not type this command after installing the packages: sudo dpkg-reconfigure libdvd-pkg. For a more extensive answer (with screenshots) see How to Play DVD in Ubuntu 18.04, 16.04 and 14.04

According to this site , you must run

sudo apt-get install libdvdcss libdvdread4 libdvdnav4

in a terminal, then open VLC, and open the disc. Keep in mind the the packages are non-free.Also if that doesn't work, try

sudo apt-get install libdvd-pkg

which is the instructions for Ubuntu 15.04 and later according to this site.
You might also want to try a different disc, to check if it is your computer or the DVD itself. Rebooting may also help.

If all else fails, try using something like brasero to create an ISO of the disk, then open the ISO in VLC. Keep in mind that it may take a while.
