Well, it seems I have found the problem.
I am shooting in PH 1080/25P, but PP CS5 seems to think the footage is 1080i ??
See the setting of my clip when I create a sequence "from clip"
My camera is set to PH 1080/25P, yet PP seems to think it is 1080i ???
The AF100 is well known as having TRUE 1080/25P or 1080/30P and now 1080/50P (Australia) and 1080/60P (Rest of the world), however PP is showing that it is i, not P?
Any thoughts??
Thanks again
