I currently have a variety of Kona 3, Kona Lhe, and AJA IO LD video cards/boxes at my post facility. All of the AJA products are installed/connected via firewire to MacPro CPU's (both Quad and 8-cores). Recently I upgraded our entire post facility to Final Cut Pro version 6.0.5 and now I'm having problems maintaining a consistent video signal. We could be digitizing an hour long tape or playing back a sequence however we always have to refresh the video and audio signal through Final Cut Pro because at some point every hour we lose video signal out of the AJA I/O LD. Any ideas on what maybe causing the loss of video signal? I can't find anything on AJA's site that notifies customers of a conflict between the I/O LD box and FCP 6.0.5. Please note that we do not have any of these problems with our edit bays that have Kona LHe and Kona 3 cards.
