This one:

#!/bin/sh

dir=$TMPDIR/$$
cwd=`pwd`
disp1=$1
disp2=$2
shift
shift

mkdir -p -m 700 $dir
cd $dir

mkfifo $dir/stream.yuv
mkfifo $dir/mp1
mkfifo $dir/mp2

(cat stream.yuv | tee mp1 > mp2 ) &
mplayer -nocache -quiet -vo x11 -display $disp1 mp1 & 
mplayer -nocache -quiet -vo xv -display $disp2 mp2 &
mplayer -nocache -vo yuv4mpeg -slave -quiet "$1"

cd $cwd
rm -rf $dir

-ao is esd or oss - doesn't matters.

I'll try it and if it persists will post -v logs.

Well not.  Two separate videos (even three) with _separate_ audio streams
it plays w/o problems.  If I play the same file with separate instances of
mplayer it does ok.  Framedrop is only when I du mpmult.sh

Hmm...
