How do you make MPlayer to display in full screen?

[exe163]

For some reason VLC starts very slowly and lags when playing some H264 in mkv anime. So I turn to Mplayer. Is there a way to make it full screen. I tried every button but none seems to work.

EDIT: It takes full 20 seconds to get the video playing with VLC, while MPlayer starts instantly. I can't figure out why.

You can also try Movist.

As to FULLSCREEN - CMD+F or the MENU BAR.
