[MPlayer-users] XvMC

Using Nvidia 7950, Ubuntu Jaunty.  The packaged version of mplayer 
(1.0rc2-4.3.3) seems to utilize XvMC on my system upon command-line request.

Attempting to compile the current snapshot - the configure script does not 
detect XvMC.  I have installed the XvMC dev libraries.  Forcing compilation 
with the --enable-xvmc allows compilation to proceed without errors, but 
running mplayer results in an error.

Since the pre-compiled binary runs fine, I assume this is either something in 
the current version or a problem with my compiler environment.
