Effective technological measures ~= DRM and is taken from treaty
language. No, print wouldn't be considered an effective technological
measure. https://www.gnu.org/copyleft/gpl.html refers to the treaty

Some places CSS is apparently considered an ineffective measure, so
distributing works under any CC license on a CSS
not-really-all-that-"protected" DVD may not be an issue.

In any case, I think the GPLv3 approach of permitting circumvention
might be less problematic. There's a stub about it at
http://wiki.creativecommons.org/4.0/Technical_protection_measures but
needs vetting.
