@tw2003 - I'm not a validating admin nor a German speaker, so won't attempt to comment directly on each case. But I am a fan of documentaries and your descriptions of them suggest to me that each could be worth pursuing. The other criterion is that the films have to be openly available - is http://swrmediathek.de a well known site which is likely to have a reasonable audience?? Have any of them been released elsewhere (eg shown on TV?? available on DVD??) If you can tick yes to either question, you may well have made a good enough case for approval.
