Hi there,
This message goes out to the people that use the pan filter and know
exactly what they are doing.

Up to now i wasn't able to fully enjoy a video encoded with 5.1 aac
since mplayer did not downmix to Stereo. After some time i found the pan
filter and played with it some time.
This is what i found working: '-af

BUT, since i don't know exactly how to handle the pan filter the
resulting Stereo output is less than optimal. Anyone out there that can
give a better line for 
5.1ch -> 2ch Stereo downmixing?

(iirc this is only needed with aac 5.1. if the audio is ac3 or ogg
vorbis mplayer will downmix automatically)
and sorry for the bad english.
