[MPlayer-users] 1080p/60fps plays fine in vlc, not in mplayer

[Grant]

I usually find that mplayer has somewhat better performance than vlc,
but the 1080p/60fps videos produced by my Sony digital camera play
smoothly in vlc but without A/V sync on mplayer.  I'm comparing 'vlc
file.mkv' and 'mplayer file.mkv'.  Does anyone know why vlc seems to
be more performant than mplayer with these particular videos?

Does mplayer take advantage of my multi-core CPU?
