with mencoder/mplayer i had no success but with ffmpeg...

you can try (like this example)

ffmpeg.exe -vn -acodec copy -i fixed1.ac3 -f wav - | oggenc2.exe --raw - -o aaa.ogg

BUT with nero it doesn't fuction...

because the "raw" format ... but it is a start

you just make a pipe, have mplayer dump the pcm to the pipe and have nero encode it under wine

example

Code:

$ mkfifo audiodump.pcm

$ wine /path/to/neroAacEnc.exe -ignorelength -q .2 -if audiodump.pcm -of soundtrack.mp4 & mplayer /path/to/movie.vob -vc null -vo null\
 -aid 128 -af -af channels=6:6:0:0:1:1:2:4:3:5:4:2:5:3 -ao pcm:fast:waveheader:file=audiodump.pcm -channels 6

Mplayer dumps 6 channel ac3 files with this channel order: 0fl, 1fr, 2sl, 3sr, 4c, 5lfe.
neroAacEnc needs the wav in this order: 0fl, 1fr, 2c, 3lfe, 4sl, 5sr

Someone else posted channels=6:6:0:0:1:1:2:4:3:5:4:2:5:3 before, and I didn't think it was right, so I did some tests, only to come up with the same conclusion.
