mplayer -v Game.of.Thrones.S01.Ep01.1080p.BluRay.DTS.x264-ESiR.mkv 2>&1|
Sorry, I tried:
mplayer -v file.mkv 2>&1| grep V:
and I got nothing out of it.

Indeed, they just released an update. I got 8.0.3 and it works too now.
Thats said, -vo xv and -vo gl look about the same to me and seem to take the
same amount of CPU.
Is -vo gl better somehow?
