Done. Surprisingly (to me,  because on another box, but without 
dxr3,I've no such problem) the segmentation fauls occurs in fontconfig 
libraries, in fact if I set "fontconfig=no" in /etc/mplayer/mplayer.conf 
  it plays ok (albeit with a single dot as osd).

Program received signal SIGSEGV, Segmentation fault.
