Awaiting test board from Blackmagic...
..only problem is that they don't have any mini-BNC to BNC adaptors in stock yet at £15.00 each!!!
(and neither does anyone else I've tried... guess they are all on the same ship from china)

Blackmagic were quoting 4-6 weeks for the cables - altough the cards were available now... Might be sent a test board in a few weeks...
