I did all of this, and no great success.  Like really, many iterations 
of profile setups, xorg.conf options, and all I got was a small drop in 
CPU and lessened frame drops.  Like I mentioned before, Internal player 
was choppy and high CPU, Mplayer and Xine on the SAME file was low CPU 
and no dropped frames or jitter.  Internal player seemed to be the 
culprit to me.
