I’ve been banging my head with what seems to be the same problem. I’m using FCP 5.0.4. BSP Deck – UVW1800 thru AJA’s IO w-422 interface.
I’ve dig’d a clip with burn-in. The burnin and the timecode reader thru FCP are giving me shifting results. At times, the two match, generally they don’t – as much as 5 frames off. I’ve called AJA, and several posthouses in town with no happy solution. I also have FCP 4.5 running on the same system (not recommended) and it too is having the same problem. i’ve been told to put 4.5 on another driver. Haven’t tried this yet, hoping the problem is elsewhere.
