  <title>DVD を再生できない</title>

  <p>DVD をコンピューターに挿入しても再生できない場合、DVD の<em>コーデック</em>がインストールされていないか、DVD の<em>リージョン</em>が異なる可能性があります。</p>

<section id="codecs">
  <title>DVD 再生に適したコーデックをインストールする</title>

  <p>In order to play DVDs, you need to have the right <em>codecs</em>
  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.</p>

  <p>DVDs are also <em>copy-protected</em> 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.</p>

<section id="region">
  <title>DVD のリージョンを確認する</title>

  <p>DVDs have a <em>region code</em>, 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.</p>

  <p>DVD プレイヤーの中には、リージョンを変更できるものがあります。しかしこの変更は、DVD プレイヤーがリージョンをロックするまでの数回に限られます。コンピューターの DVD プレイヤーのリージョンを変更するには、<link href="http://linvdr.org/projects/regionset/">regionset</link> を使います。</p>

  <p>You can find
  <link href="https://en.wikipedia.org/wiki/DVD_region_code">more information
  about DVD region codes on Wikipedia</link>.</p>
