  <title>Why won’t DVDs play?</title>

  
If you insert a DVD into your computer and it doesn’t play, you may not

  have the right DVD codecs installed, or the DVD might be from a

  different region.

  <title>Installing the right codecs for DVD playback</title>

  
In order to play DVDs, you need to have the right codecs

  installed.  A codec is a piece of software that allows applications to read a

  video or audio format. If your movie player software doesn’t find the right

  codecs, it may offer to install them for you. If not, you’ll have to install

  the codecs manually — ask for help on how to do this, for example on your

  Linux distribution’s support forums.

  
DVDs are also copy-protected using a system called CSS. This

  prevents you from copying DVDs, but it also prevents you from playing them

  unless you have extra software to handle the copy protection. This software

  is available from a number of Linux distributions, but cannot be legally used

  in all countries. You can buy a commercial DVD decoder that can handle copy

  protection from

  <link href="http://fluendo.com/shop/product/oneplay-dvd-player/">Fluendo</link>.

  It works with Linux and should be legal to use in all countries.

  <title>Checking the DVD region</title>

  
DVDs have a region code, which tells you in which region of the

  world they are allowed to be played. If the region of your computer’s DVD

  player does not match the region of the DVD you are trying to play, you won’t

  be able to play the DVD. For example, if you have a Region 1 DVD player, you

  will only be allowed to play DVDs from North America.

  
It is often possible to change the region used by your DVD player, but it

  can only be done a few times before it locks into one region permanently. To

  change the DVD region of your computer’s DVD player, use <link href="http://linvdr.org/projects/regionset/">regionset</link>.
