Doesn't appear to be for me. Without tweaking the settings it's rather choppy. Took a while to find the dspmp3 setting for me. And I have a rather new(est?) mplayer that has the nice GTK frontend...



EDIT: There was a mplayer config file in /home/user/.mplayer/config with vo=sdl etc... probably put there by an older mplayer installation because I don't recall putting it there.
