That depends on *which* GeForce card you have.  vdpau will only help you
if you have a GeForce 6 series card or later *and* are running with the
nvidia driver.  The more later, the more it can help you.  If you are
using nouveau or nv, you can't benefit from vdpau support.

DRI = Direct Rendering Infrastructure.  It is the main support for 3D
acceleration in X11 these days.  In the video world, DRM is the Direct
Rendering Manager.  Wikipedia is your friend.

Whoa!  This looks like you have a Radeon card of some sort.  Radeon is
made by AMD these days (used to be ATI).  GeForce is made by nVidia.

Yeah, I get this message from both my laptop and my desktop.  The former
has an ATI chipset, the latter an nVidia one.

What is in your /etc/mplayer/mplayer.conf file?  It should show the vo
options it will try and use.  Mine uses:

vo=xv,xvidix,

and I don't have those problems....  The man page for mplayer for video
output options.  You can override by using the -vo command line option.
See what works best for you.
