same with this URL:
http://www.arte.tv/guide/de/044992-008/frankreichs-mythische-orte?autoplay=1
On the web, they play fine, but they will be removed from the server soon I'm afraid, they are only online for 7 days.

Both videos are unavailable now. However downloading works fine for another videos from frankreichs-mythische-orte series.
