Facebook Sharing

Hi there,

I am currently using KalturaCE to provide videos sharing capabilities to my websites.
Almost everything works like a charm, but the share feature in the KDP :

Once shared in facebook, the video is visible (meaning that the player loads and the browser retrieves the FLV files) but the player can't be started.

Do I need to register somewhere to make it work ?

Thank you in adavnce for your help.

PS : It is my first post, here, I don't even know if I ask in the good forum.
Please excuse me if I am wrong.
