I think vo=xv is the default.  I just tried mplayer on a machine with
the default, nearly-empty .mplayer/config file, and spotted the
following line in the console output.

VO: [xv] 640x480 => 640x480 Planar YV12 

I added v0=x11 to the config file, ran mplayer on the same file, and
got this in the same place.

VO: [x11] 640x480 => 640x480 BGRA 

The video played both ways, so this machine (not the one I'm having
trouble with) can handle xv or x11.  The one I'm having trouble with
seems to be unable to play xv.  I think this has something to do with
the i915 driver, so I'll pursue that and come back.  Thanks for the
debugging advice.
