I know its not Belegarth, but Wreckreation Nation (Discovery Channel) is airing some footage of "Dagorhir: Battle of Badon Hill." Seems like the closest footage on prime time of our/similar sport. I believe the episode of Dagorhir airs tonight (1/20). Didn't see another post on this, so sorry in advance if its a double post.
