I was wrong there. The problem was caused by something else. You must
use the -benchmark option to make the displaying mplayer instances play
as fast as possible (i.e. as fast as the controlling instance decodes).
This should maintain A-V sync enough for me, if not you can still use
the -delay option for minor adjustments.
