you could have a look at the MPlayer-W100
http://atty.skr.jp/WebSVN/log.php?repname=mplayer-w100 : it has a fair
deal of new optimizations all over, but none have been backported to
our tree.

If ever you can make good patches out of mplayer-w100 don't hesitate
to submit them back here.

NB: some of the optimizations involve using intel's IPP library.
