Hi guys,
with the latest available win32 build of mplayer 1.0pre5 (bug also
applies to older versions), the usage of 'mplayer -identify' on a
videofile containing AC3 5.1 audio falsely reports 2ch. Example:

ID_FILENAME=t.a.t.u._-_all_the_things_she_said.vob
ID_VIDEO_FORMAT=0x10000002
ID_VIDEO_BITRATE=5400000
ID_VIDEO_WIDTH=720
ID_VIDEO_HEIGHT=480
ID_VIDEO_FPS=29.970
ID_VIDEO_ASPECT=1.3333
ID_AUDIO_CODEC=a52
ID_AUDIO_FORMAT=8192
ID_AUDIO_BITRATE=448000
ID_AUDIO_RATE=48000
ID_AUDIO_NCH=2
ID_LENGTH=421

granted, most musicvids are 2ch, but this one is true 5.1 it's the
same on any other 5.1 movie also.

ID_AUDIO_NCH=2 is always true
