Why do you link to YouTube at all? It's preferred and recommended by the club to only use http://media.ccc.de . I really wonder.
Because I watch everything on YouTube (I use YT playlists heavily to organize my to-watch-lists and access it from different devices independently of CCC talks), and the YT player embeds nicely in Twitter, and the YT video links to http://media.ccc.de but not vice versa.
So you are saying they deliberately make the http://media.ccc.de links less useful by omitting information from them and then wonder why people prefer to share the link that contains a superset of that information? 
Twitter may be over capacity or experiencing a momentary hiccup. Try again or visit Twitter Status for more information.
I'll always post the link to the original language YouTube video. Translations and other formats can be found on
