Bob –
I’m getting the same problem, but the bigger issue is, I’m not getting any picture into my UVW-1800 out from FCP. I’m working with a KONA 3 card, Gen10 Sync Generator and a K3 breakout box. I’ve tried putting the sync into all the suggested inputs. I’ve got the component cables from the break out box (Vid Mon Out) running to the 1800 inputs. My audio is fine and coming through. The ‘NO REF!’ error must be due to the picture, because it’s still laying down the TC from FCP. Any thoughts?
