I founded two bugs / errors on prosiebenmaxx.de: There is a Error 404 and a mafunction in the drm-protection-check. I posted both logs above.
There are some clips, where I get the 404 Error (e.g. the link above). I tryed to download it serveral times, but youtube-dl answered the same 404 Error. Maybe in the extractor there are some lines, that are not working anymore?
Futhermore the drm-protection check is not working. For example youtube-dl answered, that the clip is drm protected. In the header of the side, one can read,  that there is no drm protection:
meta data-react-helmet="true" property="video:drm" content="0"
I downloded the clip manually and vlc can play that clip.
I am sorry for my english. I know it is not quiet good, but I hope, I posted a helpful log.
