Advice on streaming video via xbmc

Hi,
There's this windsurfing contest on in Pozo this time every year and I always struggle to get the feed viewable on the xbmc (running on my appletv1).
This year I can't get it to work at all, not sure what else to try!

If anyone has any idea how I can watch the contect (live link below) on my TV with XBMC I would be eternally grateful.

The contest hasn't started yet but the feed is live.

I have navi-x on there, and boxee, but hoping there's a way to do it with xbmc is it just works so well usually.

Thanks

Oh, and if I use a sniffer to get more details on the video source, I get this info:
