It's interesting that the request came from someone from within the Beeb. On their own website they allude that unless you're a customer of one of the listed ISPs, you probably aren't getting a service delivered via multicast (although, I'm not sure how up to date this page is): http://www.bbc.co.uk/multicast/tv/home.shtml Cheers, James.
