hey
I’m having the same problem as you : just the playback on my external monitor driven by Blackmagic not following, sticking to a frame, although all settings seem correct. Interested to know if you solved it eventually.
I’m working on a Mac Pro 2×2.93 Ghz Quad core Intel Xeon with 8GB Ram, Final cut pro 7 and Blackmagic.
I’m not really a hardware genius so here’s all the info from System profiler
Graphics card is NVIDIA Geforce GT 120. It’s in slot 1 and also serves as PCI card, along with pcibdbd.a120 in slot 3
i’ve got 4 2GB ram chips in slots 1 2 and 5 6, leaving 3 4 and 7 8 empty. They’re DDR3 ECC type chips.
I would really appreciate your feedback.
Thanks
