Intensity Pro does not capture Progressive Video

I have connected a 3-Chip industrial Camera via YUV to the intensity Pro. I record via Media Express. It's working good, as long as I record in 576i. But if I choose 576p and run my camera in progressive mode, media express will not be able to display and record this signal. It stutters and has black images all the time.
How can I be able to record Progressive Signal 576p from my 3-Chip industrial Camera connected via YUV?
