That's a standard X error.  It means that the application (in this case, 
player) was unable to open a window with the X server.  Common causes 
include:

- The DISPLAY environment variable is set incorrectly.  If set, that 
variable should point the correct X server (if you're running player 
locally, DISPLAY should be ":0.0").

- You don't have permission to pop a window on the given X server.  If 
you're running player from a remote machine, use xhost to grant display 
permission to the remote machine.

- You're not running an X server.  In that case, start one.
