I continue to search : mplayer plays this show perflectly over hdmi
audio with :
mplayer -ao alsa:device=hdmi 1051_20091111211700.mpg

In myth, if I setup Audio output device to ALSA:hdmi : same problem :
just background sound (music, noise) but no voice. I also tried
surround40 or surround41 or surround50 but nothing happy.
