[MPlayer-users] Mencoder and AC5.1 audio

[gigyz]

Hi to all,
when i encode a dvd with mencoder and -oac copy option the encoded movie works fine with MPlayer but when i try to play it with any windows player audio don't play correctly, i think because windows recognize audio as 2 channels pcm stereo. How can i solve that ? If i edit file with a hex editor to change the file's header...???

P.S: Sorry for my bad english.
