Hi can anyone help with this...

When I try to playback my video, the preview screen goes bright green every other frame. Does anyone know why this is and how I can stop it? I reckon that because I transferred the product to another computer it may be some kind of security feature.
This happens both with the movie thats been imported and sample clips included with the program so I know there isnt a problem with capture.
This green flashing also occurs in full screen mode. I dont think my graphics card is at fault - but possible - its a NVIDIA Geforce 6200 with Turbocache.
I have directx 9.0c.

Cant find this problem mentioned anywhere else...
