I normally have to use "-ao alsa -ac hwac3," for my ac3 tracked recordings to 
output in AC3. In fact, since this is the default action for my use of 
mplayer for any recordings (the comma after hwac3 allows it to fall back to 
pcm for non-AC3 tracks), I placed them in my ~/.mplayer/config as:
ao=alsa
ac=hwac3, 

make sure to leave a space after the comma, at first it didn't work for me, on 
a whim I put an extra space on the line and it worked.

the only disclaimer is I have yet to try playing a DVD specificly, but I 
figure an AC3 5.1 track is an AC3 5.1 track no matter where it comes from....
