xvinfo will show you port base and number of ports, MPlayer will try to grab
and open one in the range from (port base) to (port base + number of ports - 1)
Normally this will only fail if some other application is already using the
same port (only exactly one application at a time can use a specific port).
You could try -vo gl:yuv=2, though with my card and radeonhd driver it still
only crashes - updating to 2.6.32 kernel might fix that but I haven't
tried yet.
