Huge thanks mp4 now works.  Also the mouse pointer is not trapped
inside the mplayer window as always happened before with any picture,
this is a great improvement.

Installed libxv-dev like you said and recompiled #
DEB_BUILD_OPTIONS="--enable-runtime-cpudetection" debian/rules
binary  .

You know it is perhaps a bit irritating for you hackers but it saves
me a vast amount of work.  So thanks again.

Incidentally also needed:  apt-get install libvdpau-dev  .  Using
nvidia proprietary drivers.
