1) Always post the ACTUAL command line used (or log file line two) so we know
what the site is, what ALL your settings are, etc.
2) Always post the URLs you're not getting and from what URL.
3) Always post anything USEFUL from the log file.
4) If you want everything use the near flag (get non-html files related) not
filters.

download.php?name=x could be anything. It could be an html that contains a wav

If the site is really broken, just rename the download.php to .wav and you
have your file.
