Ziggo does not encrypt any channel that I'm actually using anymore. As for the setup, I do know what I'm talking about, I've been the maintainer of FFdecsawrapper for about 3 years now. For basic instructions (a how-to) look at my wiki pages: http://www.lursen.org/wiki/FFdecsawrapper_with_MythTV_and_Oscam_on_Debian/Ubuntu http://www.lursen.org/wiki/Speciaal:AllePaginas Aren't we lucky to live in The Netherlands?
