You might try playing with the -monitoraspect and -screenw, -screenh 
options. Mplayer might be trying to use a resolution that PAL doesn't 
support, so it fails rather than picking another resolution. When I was 
using it, I set the aspect to 1.5 to get it to use the 720x480 instead 
of 640x480 (in fullscreen mode).
