Little correction:
To get CPU usage of video out, add system time and VO: time!
system is 0% for mga, because the whole video out process is done
by libvo, while with X output (x11,xv) blitting is done by the X server
(happens outside of mplayer -> it's systime then) but VO is still >0,
because colorspace conversion, subtitles is made by libvo.

so, to get video cpu usage:
mplayer -benchmark -nosound file.vob
add Sys and VO times, and divide by total time!

It works only with -nosound.
with sound, systime will contain usleep and ioctl waiting times too!
