I remember this been a monumental pain to set up, unfortunately the
camera died in a flood so we no longer have anything to refer back to.
We did use http://capture.sourceforge.net/ apparently. Whether we used
this directly or just gained ides/info from it we can't remember, but it
may be of some use even though it doesn't mention your camera.
