<title>Why won't DVDs play?</title>
22
<p>If you insert a DVD into your computer and it doesn't play, you may not
23
have the right DVD <em>codecs</em> installed, or the DVD might be from a
24
different <em>region</em>.</p>
27
<title>Installing the right codecs for DVD playback</title>
28
<p>In order to play DVDs, you need to have the right <em>codecs</em> installed.
29
A codec is a piece of software that allows applications to read a video or
30
audio format. If your movie player software doesn't find the right codecs, it
31
may offer to install them for you. If not, you'll have to install the codecs
32
manually - ask for help on how to do this, for example on your Linux
33
distribution's support forums. You'll probably need to install the packages
34
<app>gstreamer0.10-plugins-ugly</app> and <app>libdvd0</app>.</p>
36
<p>DVDs are also <em>copy-protected</em> using a system called CSS. This
37
prevents you from copying DVDs, but it also prevents you from playing them
38
unless you have extra software to handle the copy protection. You can buy a
39
commercial DVD decoder that can handle copy protection from
40
<link href="http://www.fluendo.com/shop/product/fluendo-dvd-player/">Fluendo</link>.
41
It works with Linux and should be legal to use in all countries.</p>
45
<title>Checking the DVD region</title>
46
<p>DVDs have a <em>region code</em>, which tells you in which region of the
47
world they are allowed to be played. If the region of your computer's DVD
48
player doesn't match the region of the DVD you are trying to play, you won't be
49
able to play the DVD. For example, if you have a Region 1 DVD player, you will
50
only be allowed to play DVDs from North America.</p>
52
<p>It is often possible to change the region used by your DVD player, but it
53
can only be done a few times before it locks into one region permanently. To
54
change the DVD region of your computer's DVD player, use
