Dailymotion fullscreen button/airplay stopped working

[ins0mniac]

I have been viewing embedded dailymotion videos in Safari on my new Ipad without any problem. I use the fullscreen button on the video panel, the airplay button then appears and there it goes to my ATV. Suddenly the fullscreen button stopped working (I'm still on iOS 5) a few days ago.

Any clues would be welcome.
