Hi,
Having a similar problem except I disagree with the answer above. I have 2 firewire DV devices connected to a single bus. Different models of camera, plugged into a firewire hub and then into the computer QLab will happily display both of them though, so I can't see how its an inherent firewire design flaw. Why can't Isadora show me both inputs? Is there a work around other than buying some USB hardware? Thanks
