[MEncoder-users] ac3 5.1 question

[Andriy Babiy]

Hi everybody.

Could anyone advise me on which option should I use to build mplayer to 
make them recognize ac3 5.1 audio?
Everything was OK with that; then, I rebuilt mplayer and changed some 
options. Frankly speaking, I can't remember what exactly. Now, I have:

What did I break? How can I get it back? I know it worked, and should work 
now.
Thank you very much in advance!
