> As a consequence, unlike the English WIkipeida there are no CD/DVD/game/music/book covers/product images on the German WIkipedia. This is a problem for many Wikipedias, which CC might contribute solving beyond the prinicple of open content on commons. 

	Maybe I overlooked something there, but I don't understand how allowing CC-BY-ND works would solve the problem of CD/DVD/game/music/book covers. Abbey Road, Star Wars, Civilization or Twilight covers are not released under any CC license, are they?
