Okay, thanks for your hint ;)

-c:a is not recognized on my ffmpeg version: FFmpeg version
SVN-r0.5.9-4:0.5.9-1

So, thanks for the clarification, that -c:a is the same as -acodec copy.


And now, I could really try your hint: mplayer has dumped a file with
80kbit/s @ 32000Hz.

ffmpeg has "converted" it to an 128kbit/s @ 44000 Hz (eyeD3 has detected
both informations). So, all should be fine.

How does ffmpeg know, that this is a 128kbit/s file?

Anyway, thanks for your help!
