Tried nowaveheader. No luck.

Also tried:

ffmpeg -i test.dv -vn -acodec pcm_s16le -ar 48000 -ac 2 audio.wav

That also didn't work if audio.wav is a fifo.

Why in the world does mplayer (ffmpeg) care if audio.wav is a fifo?

Also tried:

ffmpeg -i test.dv -vn -acodec pcm_s16le -ar 48000 -ac 2 - | \
    neroAacEnc -ignorelength -q 0.5 -if - -of audio.mp4

That also didn't work:

Input #0, dv, from 'test.dv':
   Duration: 00:04:51.55, start: 0.000000, bitrate: 28771 kb/s
     Stream #0.0: Video: dvvideo, yuv411p, 720x480, 28771 kb/s, PAR 8:9

Unable to find a suitable output format for 'pipe:'

Puzzled, but resigned to making big temp files.
