Ask YC: What is the url of this clip? (to annotate Doug Crockford's Javascript video)

(playing Doug Crockford's Javascript videos in FLV Player).

I wrote an annotation tool and am using Jeroen's FLVPlayer to play clips so they can be annotated. I realized with dismay that I cannot extract the url of the video. Can you please tell me how to extract the url from the embed tag?
