[MEncoder-users] Dolby downmix

[Rolf Ernst]

Can someone clarify this for me, please?

I am trying to do a Dolby Surround downmix from an AC3 5.1 a/v file. I 
have found many different comments from many different sources with many 
different observations and comments.

Can someone clarify this for me?

This is the command line I have seen that supposedly dumps the audio via 
filter as Dolby surround into a wav file. Is this true?

mplayer inputfile -channels 6 -af channels=2 -vc null -vo null -ao 
pcm:fast:file=audio.wav
