My theory now is that those are not errors, even though they are written to xerrs.log, unless that makes them errors by definitionI get no errors in xerrs.log if I use gnome-mplayer in pupradio.

One can see in the mplayer command line above that gnome-mplayer send the -quiet option, but that is still more info than we want.
