Brian,
I think I’m very similar situation like you. We recently upgraded our church video system with ATEM2. With that, we also bought Triplehead2go along with propresenter software. When we were trying to connect output of triplehead2go with BlackMagicdesign video hub through DVI extender, it just didn’t work. Later, we found out this setup won’t work. I’ve been trying to find a solution for this last several months…
So, have you purchased Matrox DVI converter? It looks like I might have to follow this route. Let me know how this works out for you.
Thanks.
Peter
