  This values depends at quality of your monitor (and setting of controls
  Defaultd settings should be OK for most PC monitors. But ideal monitor
  Needs dimmul=1.71 boldmul=1.43. For example monitor used by SGI is very
  close to this values. Also old 14" vga monitors needs higher values.

Additional options vo_aa provides:
  help        print this help message
  osdcolor    set OSD color
  subcolor    set subtitle color
        the color parameters are:
           0 : normal

           2 : bold
