Anybody correct me if I'm wrong, but the presentation is a remix and
Share-Alike (or ND) conditions of licenses of the remixed works apply
to the remix: http://wiki.creativecommons.org/FAQ#Can_I_combine_works_that_use_different_Creative_Commons_licenses_into_my_work.3F

So "SA" enforces the license of the whole presentation.
