Thank you for your prompt respone. The debug info is deleted.
I do have a Dreambox (and also 2 Mut@nts), but all with the OpenPLi image on it (also on the Dreambox). But I also have both DVB-S and DVB-C (Ziggo) tuners in them. The EIT comes from a Ziggo DVB-C channel so maybe they send this information in the EIT as they have a very comprehensive guide (the EIT's that do work seem indeed to come from sat).
No hurry, I'm glad you have found the cause and are willing to spend your precious time in updating the plugin with these descriptors. I will watch this thread and when 1.6.0 comes out download it.
Have a nice Sunday.
** Edit ** If you follow this link (from a random program tonight on the channel the EIT came from) you'll see he informatio Ziggo has in the EPG (and there I do see the mentioned descriptors like age 12 for this particular movie and content Komedie). So I think it is not really caiused by the image, but more that the EIT provider sends more extended information including more descriptors
