That's not the driver, that's the name of the video output plugin that mplayer
uses (see below.)

Well it seems like your hardware is fast enough, you could always try playing
video with the options "-vo null -ao null" which won't give you a picture or
sound, but it will tell you whether your CPU is powerful enough to decode the
video.

Well I was going to say it's probably slow because of -vo x11 (it's not smooth
on my 1GHz Athlon) but the problem you describe sounds more like your CPU
isn't fast enough...

You've only posted the last few messages, we need everything mplayer prints

Well at least it appears the audio isn't interfering with the video.

What happens if you play another file type? The RealMedia codecs might not be
working quite so well for you, so if possible try playing a well-tested
format like MPEG or DivX AVI and see if they have the same problem.

Actually you've misinterpretted what he meant (which is understandable, they
both have the same name...) The x11 and xv *plugins* that you use with
mplayer's -vo option are different methods of displaying the picture on your
screen, but the X11 driver that was mentioned is an entirely separate program
which controls your video card.
Tobias just meant that the driver X-Windows is configured to use is the
correct one, because if it was the wrong driver you probably wouldn't get
anything out of "xvinfo". (If you're curious, the name of this driver is
located in your X-Windows configuration file, "XF86Config".)
If your version of X-Windows is a little old, you could always try upgrading
it to see if it comes with a newer version of your video card driver (which
might contain fixes that make mplayer's xv plugin work properly.)

Perhaps it's not compiled into your kernel.
Cheers,
Adam.
