I know this does not scale very well but DV's are special:
$ ffmpeg -ss 1 -i input -vcodec copy -f rawvideo out

out is now a dv file with audio.

As explained by Micael, the issue is that the beginning of the file contains
broken frames.

ffplay allows you to press "a" while playing to enable the newly-found
audio stream with your original sample.
