FFmpeg can be forced to use the external/system libVorbis library by passing:
-acodec libvorbis
as part of the FFmpeg command line.
Note that passing '-acodec vorbis' is incorrect and requests the low-quality built-in FFmpeg-internal Vorbis encoder.

I foun an old version an it works fine but a new compile (from windows binary page), does not.
Try one of the win32 builds from here:
http://ffmpeg.zeranoe.com/builds/ (http://ffmpeg.zeranoe.com/builds/)
use '-acodec libvorbis' and NOT '-acodec vorbis'
You could also use oggenc from: http://www.rarewares.org/ogg-oggenc.php (http://www.rarewares.org/ogg-oggenc.php)
