Have we read the same messages?
I certainly didn't get the feeling that this is a "consensus", quite
the opposite.
I've had X using 100% of the CPU time using nvidia drivers and Xv when
the refresh rate of the screen match exactly the framerate of the
video.
Like playing a 24fps video on a 24Hz screen.
There's a work-around for this, though it doesn't work for everyone,
is to add a
Option "UseEvents" "True"
in your device section

The log are there for that too ...
