Yes, I use the same script that checks the code out and recompiles

./configure --prefix=/usr --enable-xvmc

How do I bisect this as ffmpeg is updated with every configure? Or is
this just an mplayer svn break?

This does fix it and it works. The odd part is that I can switch
between the two versions of mplayer and it breaks and one and works in
the other so that leads me to think that it is in the mplayer code.
