For the complete list of available options, please read the man page.
The syntax to play a standard DVD is as follows:
</p><pre class="screen">
mplayer dvd://<em class="replaceable"><code><track></code></em> [-dvd-device <em class="replaceable"><code><device></code></em>]
</pre><p>
</p><p>
Example:
</p><pre class="screen">mplayer dvd://1 -dvd-device /dev/hdc</pre><p>
</p><p>
If you have compiled <span class="application">MPlayer</span> with dvdnav support, the
syntax is the same, except that you need to use dvdnav:// instead of dvd://.
</p><p>
The default DVD device is <tt class="filename">/dev/dvd</tt>. If your setup
differs, make a symlink or specify the correct device on the command
line with the <tt class="option">-dvd-device</tt> option.
</p><p>
<span class="application">MPlayer</span> uses <code class="systemitem">libdvdread</code> and
<code class="systemitem">libdvdcss</code> for DVD playback and decryption. These two
libraries are contained in the
<span class="application">MPlayer</span> source tree, you do not have
to install them separately. You can also use system-wide versions of the two
libraries, but this solution is not recommended, as it can result in bugs,
library incompatibilities and slower speed.
</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
In case of DVD decoding problems, try disabling supermount, or any other such
facilities. Some RPC-2 drives may also require setting the region code.
</p></div><p><b>DVD decryption.聽</b>
DVD decryption is done by <code class="systemitem">libdvdcss</code>. The method
can be specified through the <code class="envar">DVDCSS_METHOD</code> environment
variable, see the manual page for details.

DVD drives nowadays come with a nonsensical restriction labeled
<a class="ulink" href="http://en.wikipedia.org/wiki/DVD_region_code" target="_top">region code</a>.
This is a scheme to force DVD drives to only accept DVDs produced for one of
the six different regions into which the world was partitioned. How a group
of people can sit around a table, come up with such an idea and expect the
world of the 21st century to bow to their will is beyond anyone's guess.
</p><p>
Drives that enforce region settings through software only are also known as
RPC-1 drives, those that do it in hardware as RPC-2. RPC-2 drives allow
changing the region code five times before it remains fixed.
Under Linux you can use the
<a class="ulink" href="http://linvdr.org/projects/regionset/" target="_top">regionset</a> tool
to set the region code of your DVD drive.
</p><p>
Thankfully, it is possible to convert RPC-2 drives into RPC-1 drives through
a firmware upgrade. Feed the model number of your DVD drive into your favorite
search engine or have a look at the forum and download sections of
<a class="ulink" href="http://www.rpc1.org/" target="_top">"The firmware page"</a>.
While the usual caveats for firmware upgrades apply, experience with
getting rid of region code enforcement is generally positive.
