== Setting DVD Region Codes ==
== Setting DVD Region Codes ==
If your DVD player regularly locks up when you try to play back a DVD, your DVD player probably does not match the DVD's [[UbuntuHelp:WikiPedia:Regional_lockout|Region Code]]. Region Codes are a form of vendor lock-in. For example, you cannot play a DVD published in Japan (Region 2) on a DVD player in the United States (Region 1) without changing the Region Code of the DVD player (unless you own a region free DVD player). You can view or modify the Region Code of your DVD drive with the [http://linvdr.org/projects/regionset/ regionset] tool.

Most commercial DVDs are encrypted with CSS (the Content Scrambling System), which attempts to restrict the software that can play a DVD. By installing the libdvdcss2 package you can play encrypted DVDs with:

Note : While Totem-gstreamer can play a DVD automatically when it is inserted into the DVD drive, it cannot navigate the DVD reliably (see Bug #41335). If you use vlc media player you can navigate through the menu, forward in the movie and select subtitles. Just select open disc, probe Disc(s) and click ok.

Installing libdvdcss2

Ubuntu 8.04.1 (i386)

  • Install the libdvdread3 package (no need to add third party repositories) via Synaptic or command line:
 sudo apt-get install libdvdread3
  • The open a terminal window and execute:
 sudo /usr/share/doc/libdvdread3/install-css.sh

Ubuntu 8.04 (amd64)

  • Open a terminal and type

sudo apt-get install build-essential debhelper fakeroot press the enter key.

  • Then type

sudo /usr/share/doc/libdvdread3/install-css.sh press enter again

  • When it asks you, press enter to continue and it will build and install libdvdcss2

Ubuntu 7.10 and before (i386)

  • Install the libdvdcss2 package after adding the unsupported third-party repository Medibuntu.

If you are using Ubuntu 6.06 "Dapper Drake":

  • Install the libdvdread3 package from the universe repository.
  • Open a terminal and type

sudo /usr/share/doc/libdvdread3/examples/install-css.sh and press the enter key. This will download and install libdvdcss2.

If you are using Ubuntu 6.10 "Edgy Eft":

  • Install the libdvdread3 package from the universe repository.
  • Open a terminal and type

sudo /usr/share/doc/libdvdread3/install-css.sh and press the enter key. This will download and install libdvdcss2.

Your DVD player should now play back encrypted DVDs. Legal Warning: Check with your local laws to make sure usage of libdvdcss2 would be legal in your area.

Setting DVD Region Codes

If your DVD player regularly locks up when you try to play back a DVD, your DVD player probably does not match the DVD's Region Code. Region Codes are a form of vendor lock-in. For example, you cannot play a DVD published in Japan (Region 2) on a DVD player in the United States (Region 1) without changing the Region Code of the DVD player (unless you own a region free DVD player). You can view or modify the Region Code of your DVD drive with the regionset tool. IconsPage?action=AttachFile&do=get&target=warning.png <

  • To change the Region Code of your DVD player, insert a DVD from your region in the DVD player, and do the following:
  • Install the regionset package from the Universe repositories.
  • To launch regionset, issue the command
regionset

Troubleshooting

  • Jerky Playback

If DVD playback is noticeably choppy or burning a CD/DVD is slower than it should be, then you may need to enable DMA transfer for the DVD drive. See the DMA (Direct Memory Access) page for details.
