I was wondering, sometimes 5.1 AC3 seems to be tagged as stereo...I've got a DVD here, where KMPlayer says it's stereo, but both MediaInfo and ffdshow show it as 6 channels.
too bad my "stereo <> 6 channels" rule in ffdshow audio doesn't work and reverts to stereo...yet it shows as 6 channels input in ffdshow audio, I guess I'm SOL?
I've put a sample here:
