[MPlayer-users] How can I hear dts?

[Pepe]

In a DVD, when I select one of the audio tracks (identified by mplayer as 
"audio stream: 2 format: dts (5.1) language: es aid: 137"), instead of sound 
I hear a very annoying noise.

This is what mplayer says:

Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
Cannot find codec 'dts' in libavcodec...
ADecoder init failed :(
ADecoder init failed :(
