I am not sure either. This is what I get when I run xine-check.
""[ hint ] DMA is disabled for your DVD interface.
This will probably result in a serious performance hit when
playing DVDs. You can issue the command
hdparm -d1 /dev/hdg
as root to enable DMA. It would be wise to add this command to
some script that is executed executed at boot time.
Note that you probably have to set the DMA mode for your drive as well.
Most DVD-ROMs work fine with multiword DMA mode 2. You can use
hdparm -d1 -X34 /dev/hdg
(as root again) to set this mode. Maybe UDMA2 will give you even better
performance, but it only works well with some controllers. You'll
probably need UDMA capable IDE cables for this mode. If you want
to try: make backups of your important data and type (as root again)
sync
hdparm -d1 -X66 /dev/hdg
If your System still works fine after this, you probably want to keep
these settings (add them to some boot script).
If your system hangs or behaves very strangely after a few minutes, you
should reboot immediately and never use this setting again on this
machine. Good luck ;-)

[ good ] found xvinfo: X-Video Extension version 2.2
[ hint ] Your X server doesn't support YV12 overlays.
That means xine will have to to color space transformation and scaling
in software, which is quite CPU intensive. Maybe upgrading your
X server will help here.
If you have an ATI card, you'll find accelerated X servers on

[ hint ] Your X server doesn't have any XVideo support...
XVideo is an X server extension introduced by XFree86 4.x. This
extension provides access to hardware accelerated color space
conversion and scaling, which gives a great performance boost.
If you have a fast (>1GHz) machine, you may be able to watch all
kinds of video, anyway. You will waste lots of CPU cycles, though...
