I have been trying last week to compile mplayer with "--disable-mpg123 
-- disable-mad" without success because mplayer invoke ffmp3float 
(please see here after --> mplayer "tells" me the track require a 
certain mpg123 decoder which is not available because mplayer was not 
compiled with and surprisingly replace it by a ffmp3float decoder !! )
