How do you know for certain that DD 5.1 audio is there? What players
have you tried it on?
Some receivers will lie and say they're playing 5.1 audio when they
aren't which sounds likely since you're using hwac3. We see this
confusion all the time when people declare their receivers "smarter"
than others because they see 5.1 audio when more truthful receivers
If the AC3 packets aren't tagged with 5.1 then these players/receivers
are lying about the audio they're seeing and mplayer is simply telling
you the truth.
