I have the same problem as jarrod
In OSX 10.3.8 + FCP 4.5 all worked fine withou problems, now I upgraded to OS X 10.4.2 + FCP5 and I have problem with freezing SDI output (on PAL monitor). On VGA monitor video plazed with all frames every time, on PAL monitor it freezes.
I muzst say that 10-bit clips freezes when played in timeline. 8-bit clips are sometimes o.k.
But Editing to tape or print to video dont work correctly – output freezes in 8 or 10 bit although on VGA monitor is played smoothly and without problems.
I tested change cards in slots, but no combination works.
Dual G5 2GHz machine + OSX 10.4.2. + all updates
Kona SD + Atto UL4D (Medea Videoraid RTRX) + Apple FC HBA (XRaid – raid 50, 14 drives)
