Are you sure the source isn't using dual-audio? (I.e. two-channel
audio, but one language on the left channel and one on the right
channel) If so, MPlayer sees that the recording includes dual-audio and
plays back only one channel. (Note that you can have it play that
channel to both left/right speakers to "simulate" stereo sound, but
since the source itself is not broadcasting stereo, you can not get real
stereo ouput.)
