[MPlayer-users] Problems Using Mencoder (fixed)

[Sean Zimmermann]

I downloaded and compiled the most recent cvs snapshot, and although  
it fixed the "Ignoring Video Stream" problem, it seems that the audio  
is still completely distorted (it sounds like static). I did find  
however that this only seems true with -oac mp3lame, as when I tried - 
oac faac, it worked fine.

Thank you for any help,
Sean
