My gut feeling is to blame ffmpeg's WMV muxer (it may not be able to mux
a bit-exact copy of the original video with your new soundtrack).

Try using '-sameq' instead of '-vcodec copy' (re-encode the video with
same quality rather than a bit-exact copy - this often solves muxing
issues but will cause a small loss of either video quality or increased
bandwidth).

and also try a different output format eg. 'new_video.avi' or '..mov'
instead of 'new_video.wmv'.

you may need both, this should work:
'ffmpeg -i vid.wmv -i aud.wav -sameq -map 0.0 -map 1.0 output.avi'

welcome to the world of video.

PS. yes, there are other options (lots of options for ffmpeg to
configure the muxer) and other tools. e.g. 'mencoder' provides its own
muxer-implementations for some formats.
