try as root? is mplayer part of the video group?
looks like a permissions problem.
file plays fine for me.

[VO_XV] Could not grab port 335.
can you get xvideo working on your system? its faster than x11.

Problem went away after I updated the system and rebooted.
Possibly incomplete system update is to blame.

Thank you,
Yuri
