Oops, yes I forgot to point this out in my previous mail - the option uses 
the /dev/nvidia device.  If you don't have that device then it will fall 
back to /dev/rtc and as a last resort, usleep().  But generally if you 
don't have /dev/nvidia it's not worth using it instead of the normal 
experimental AV sync option.

AFAIK running the frontend as root is recommended anyway isn't it?  Since 
the frontend likes to increase it's process priority on some threads 
(which only root can do).
