maybe.... :-)
but i still don't understand it completely....

so you're saying it all depends on the audio decoder? 
mplayer simply passes the required audio-channel-num to the
audio-decoder and then it's up to the decoder what to output ( as long
as it's channel-num is correct )?

and if so, could you provide at least for the most common situations the
numbers? :
5.1 audio and i have -channels 2
5.1 audio ...........-channels 4.. i was told that in this case the
subwoofer channel is dropped and the front middle ( or what's his name )
gets mixed into front-left and front-right... correct?

thx,
