You'll need a new version of vic and a new AG service for that to  
work. The new vic that works with the blackmagic cards hasn't been  
released yet although there are some test versions around. I don't  
have a Windows version - maybe one of the vic developers could send  
you a test version. Even then, there is still no AG service dedicated  
to the blackmagic cards so, for now, you'd have to run vic manually.  
Since the blackmagic enabled vic is so close to release, I'd guess  
that the AG service to use it will be available pretty soon.
