The mplayer program uses the specified output, and it is
preferring direct rendering if your graphics card and driver
supports it, which in case of a Radeo HD should absolutely
be no problem. However, it seems that your X currently uses
VESA, and that's why you're seeing this problem.

Sadly, graphics configuration has become quite complicated
on FreeBSD, and you need to check several things:

1. Is the correct KMS kernel module loaded?

2. Is the correct X driver loaded?

3. What output is mplayer configured to use?

You can check "kldstat" and "dmesg" output for question 1,
/var/log/Xorg.0.log for question 2, and the mplayer configuration
directory, whererever it might be today, for question 3. You
can also manually check:

	$ mplayer -vo x11 test.avi

for VESA (should always work), and

	$ mplayer -vo gl test.avi

for direct rendering (works if question 1 and 2 have been
answered with "yes").

I have a reference system (HP mini-laptop) with AMD graphics
that I can check a working configuration for.
