Blackmagic,
I have my canon Vixia connected to Blackmagic Ultrastudio Express via HDMI cable and Blackmagic Ultrastudio Express connected to MacBook Pro via Thunderbolt cable with Livestream Procaster open but there is no recognition. On the Ultrastudio product page it lists this product as working for streaming with Livestream.

What am I missing? or not understanding?

Maurice - Were you able to get this resolved? Thinking about a similar setup, but I don't want to go through all this if it won't work. Thanks.
