Problem with in-game avi and fraps

[:FI:Sneaky]

The in game .avi save just gives me a CTD and a 0mb avi file.

Fraps does not work for me in CloD, though is fine in Il2 and all other titles. I get the FPS counter in menu screens , but not on in flight 3d.

Any ideas here?

I can capture using MSI afterburner , but that's video only so have to record sound separately .
