Now i had the second video from Google which i was not able to embed to a post, as suggested in the FAQ:
Usually it works fine, but with 2 videos i have this problem. I can see a frame from the video, but if i click the play button, i get the "currently not available"-error from google.
The video itself is fine and also 'embedable', so maybe there is a problem with some charakters in the embedding-code and the db...
Has anyone else made a similar experience?
PS: Video is here:
