Drop the SetHandler then. All you need is the PythonAuthzHandler portion
and it'll do the right thing.

I do something like this:

  <FilesMatch "\.(m3u|mp3)$">
    PythonPath "sys.path+['/web/americandnb.com/python']"
    PythonAccessHandler m3u

And the m3u module does referer checking so people don't link directly
to the mp3's. If the Referer fails, we redirect to the main HTML for
that file (specific to our setup).
