with a simple analog TV encoder, some have a more advanced one.

Tested on a Toshiba Tecra 8000. Its TV output chip is miserable crap. Avoid
if possible.
</simpara> <simpara>
You must use <option>-vo vesa</option>. The tested chip was capable of
1.333333 aspect ratio only, so be sure to use the <option>-x</option>,
<option>-y</option> options and/or the
<option>-vf scale,crop,expand</option> filters if the box doesn't let
you enable TV output. Maximum resolution was 720*576 at 16bpp.
</simpara>
<simpara>
Known issues: VESA-only, 1.33333 limitation, image isn't always centered,
movie becomes 4bpp in every 10 minutes, and stays that way. Frequent hard
freezes, LCD display problems.

It has been reported that reliable TV out can be obtained by using
<option>-vo fbdev</option> or <option>-vo fbdev2</option>.
You need to have vesafb compiled in your kernel and pass
the following parameters on the kernel command line:
<option>append="video=vesafb:ywrap,mtrr" vga=791</option>.
You should start <application>X</application>, then switch to console mode
with e.g. <keycap>CTRL</keycap>+<keycap>ALT</keycap>+<keycap>F1</keycap>.
If you fail to start <application>X</application> before running
<application>MPlayer</application> from the console, the video
becomes slow and choppy (explanations are welcome).
Login to your console, then initiate the following command:
<screen>clear; mplayer -vo fbdev -zoom -cache 8192 dvd://</screen>
Now you should see the movie running in console mode filling up about
half your laptop's LCD screen.
To switch to TV hit <keycap>Fn</keycap>+<keycap>F5</keycap> three times.
Tested on a Tecra 8000, 2.6.15 kernel with vesafb, ALSA v1.0.10.
