The pauses are not necessarily determined by the X code. It's possible
that as both MPlayer and the X server start using all available CPU time
rather than waking up on events the kernel starts scheduling them in
"throughput mode" and gives them longer timeslices. You could test
giving the X server a higher priority.

Even if it does make the behavior more visually pleasing in this case
adding an XSync in that location is IMO a bad idea (as I already
mentioned in the previous mail). It can make MPlayer pointlessly wait
and waste available CPU time while the X server completes the queued
requests (perhaps running on another core or waiting for graphics
hardware).
