issue: osd does not work
fix: first of all, fonts might work in mplayer but not in gmplayer (the gui version) or the other way around. make sure you have the fonts package installed. make sure you have a subfton.ttf file in ~/.mplayer (this can be a symlink to a font from the microsoft core font package). when using the gui, select the font.desc file as the font. run "gmplayer -fontconfig". from then on osd should work. you can turn osd on and of by pressing "o".
