I've played with channel mapping a bit, and I think this is right:

Mplayer -af channels=x:y:a:a:b:b:c:c:d:d:e:e

x:0 = FL
x:1 = FR
x:2 = RL
x:3 = RR
x:4 = C
x:5 = LFE

DTS:
-af channels=6:6:0:4:1:0:2:1:3:2:4:3:5:5

EAC3:

0:x = FL
1:x = C
2:x = RL
3:x = RR?
4:x = FR?
5:x = LFE?

-af channels=6:6:0:0:1:4:2:1:3:3:4:2:5:5

I haven't found an EAC3 tech demo or test sample that gives a sound in 
each specific channel yet, so I'm having a hard time telling whether the 
rear channels are correct. Front and center seem to be OK though.
