No replies :-(
It turns out that the  --with-xvmclib=XvMCNVIDIA  to configure was 
silently failing, and the library never linked in. (I think the
configure script should have reported an error and quit.)

We can see the problem in configure.log:

cc -O4 -march=k8 -mtune=k8 -pipe -ffast-math -fomit-frame-pointer    -o 
/tmp/mplayer-conf-26278-4037.o /tmp/mplayer-conf-27338-4037.c -lXvMC 
-lXvMCNVIDIA -lXv -L/usr/X11R6/lib -lXext -lX11 -lnsl -lpthread
/usr/bin/ld: cannot find -lXvMCNVIDIA

Why not found? Ah - a missing symbolic link which I now created:

/usr/lib/libXvMCNVIDIA.so -> libXvMCNVIDIA.so.1.0.8762

Is this a problem with the Ubuntu nvidia-glx package?


Now I'm trying to get XvMC working on I810, and finding a different 
problem, that also causes silent failure in mplayer configure.

configure.log shows lots of errors like:
libI810XvMC.so: undefined reference to `drmCommandWriteRead'

So it is missing a DRM library ?!

Finally, what is the status of XvMC? There seems to be no official 
documentation, and it is disabled by default. The best I could find
was a 3-year-old FAQ in the mailing archives, (below a "beware of the 
leopard" sign.)
