External DVD driver doesn't play the disc properly

  • 772

Question: can you recommend an external DVD player that I can use for watching legal movies in Europe (region code: 2) using Ubuntu 18.04?

I bought a new notebook and an external DVD player because it didn't have one. I installed Ubuntu and installed all the necessary libdvd* packages:

ii  libdv4:amd64                               1.0.0-11
ii  libdvbpsi10:amd64                          1.3.2-1
ii  libdvd-pkg                                 1.4.2-1-1
ii  libdvdcss-dev:amd64                        1.4.2-1~local
ii  libdvdcss2:amd64                           1.4.2-1~local
ii  libdvdnav4:amd64                           6.0.0-1
ii  libdvdread4:amd64                          6.0.0-1
ii  ubuntu-restricted-extras                   66
ii  regionset                                  0.1-3.1

Then I wanted to play a DVD and got 3 pages of error messages:

$ vlc dvd://sr0

Then I connected the external DVD to my old notebook which has an internal DVD. I was able to play the DVD by the internal one but the external returned the same error messages.

Device:

$ dmesg | grep -i dvd

Troubleshooting:

  1. No disc menus:

I delete the folder related to the movie inside the ~./dvdcss folder. I ticked the No disc menus checkbox in the VLC UI then it played the DVD but it stoped when it reached 19:18 dvdread demux error: read failed for 3/4 blocks at 0x72d80

I tried to play it from command line without disc menu and it also worked: vlc dvdsimple://sr0 Then I tried to play it defining the title and the chapter but it always played the first title:

vlc dvdsimple://sr0@01
vlc dvdsimple://sr0@02

I tried to list the titles and the chapters but it resulted the same output when I tried to play it:

$ lsdvd /dev/sr0

  1. I changed the regioncode to 2 (I live in Europe) by the regionset package. Didn't help.

$ regionset /dev/sr0

regionset version 0.1 -- reads/sets region code on DVD drives
Current Region Code settings:
RPC Phase: II
type: SET
vendor resets available: 4
user controlled changes resets available: 4
drive plays discs from region(s): 2, mask=0xFD

Would you like to change the region setting of your drive? [y/n]:n

  1. I checked the values of the DVDCSS_METHOD. It was empty. I changed it to title, disc and key. None of them helped.

  2. Enables libvdpau-va-gl as the default VDPAU driver didn't help either.

  3. I installed mplayer, mplayer-gui and mencoder. Fixed the GUI error and tried to play the DVD.

$ mplayer dvd://

It recognized the chapters differently (see the Error cracking CSS key things):

Playing dvd://.
There are 41 titles on this DVD.
There are 1 angles in this DVD title.

It played the first 4 chapters of the DVD till it reached the very same moment in the film when it crashed. Interesting is that the timestamp was 40 seconds more like 19:50:

The error:

 MPlayer interrupted by signal 2 in module: decode_video
 A: 369.6 V: 369.6 A-V: -0.021 ct:  0.059 9237/9237  7%  1%  2.3% 0 0

The situation is same if I try to play other DVDs. Is it an encoding, a driver or a hardware error?

Do you have any ideas how can I fix it? Or do you have an external DVD player which works for you?

dvd mplayer xubuntu vlc 18.04

  1. I bought an Asus Zen Drive external DVD player and it works just fine.

    So the conclusion is. Do not buy Hitachi-LG external DVD player for your Debian Linux system because it might not work!

  2. My DVD drive broke and I bought a new one and got into similar issue, similar console output. The very same DVD disc on a very same Ubuntu 18.04 computer had worked before using VLC but not with the new drive. I also had all the libraries installed. I though my new drive was faulty.

    But reinstalling libraries using

    sudo apt install libdvd-pkg && sudo dpkg-reconfigure libdvd-pkg

    did the trick and now the new drive works as a charm. It might not work for the original poster, but hopefully it will help someone else with a similar problem.

    PS! I had the new drive connected to the computer while I reinstalled and reconfigured libdvd (I do not know if this was relevant or not).

    PS! Maybe just sudo dpkg-reconfigure libdvd-pkg would work too (have not tested as mine is working now). See more on Ubuntu help pages.
