 R=> As I already wrote this just can't work. You absolutely _must_ specify
 R=> -benchmark for the two slave mplayers, because otherwise all of them
 R=> will try to do timing and completely step onto each others feet,
 R=> literally speaking.  

Aha, I see..   I've tried initially to -benchmark on master instance which
failed terribly, so I've abandoned that.  Now, when I've tried -benchmark
only on slaves, it worked perfectly on the mpeg2 clip which initially
terribly framedropped.

 R=> If you have sound, the one playing the sound must (and always will)

The master instance now plays sound.  At it looks like it does it in sync
