Actually that is what I did, I just mixed up the options above. Of
course I used -oac mp3lame -ovc copy (-ovc mp3lame doesn't make any
sense anyway).

I tried

# mencoder -ovc copy -oac lavc -lavcopts acodec=ac3

and got the same error:

Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
