DM365 frame rate decimation from 30Hz to 15Hz

Hi, we're using the DM365 processor to capture live 1080i at 30 frames per second, but the DM65 is transmitting this video at 15 frames per second. We're trying to find out why the DM365 is decimating the frame rate. Here is what we know so far: The capture system is indeed capturing at 30 FPS but somehow the VPBE is making the driver run at 15 FPS. We're checking all the registers in the VPBE. The code uses a library call getDisplayBuffer() in the display thread to get a free display buffer. This is where the bottleneck is happening. If we measure the capture thread rate it is running at 30 FPS as it should. Does anyone know how to get the DM365 to transmit 30 frames per second when it is capturing video at 30 frames per second?

Thanks,
