Hey Malcolm,
Re our discussion earlier i really think the problem most likely lies in the Kona drivers. They only have support for FCP 5.1 in V3.X of the drivers and not in V2. I know you said they were unwilling to upgrade as they run from a SAN but these drivers will have absolutly inpact on it. – I would really recommend updating the Kona3 drivers to the current version: Version 3.3
When we get a bit of quiet time here i’ll run some tests! All the best
Josh
