How to read/modify the acquisition history on a frame grabber with MATLAB

Hello! I am using a national instruments frame-grabber together with a Mikrotron camera, triggering acquisition by software in MATLAB. So in my MATLAB code, I start acquisition from the camera and immediately after present an image on a projector. For calibration purposes, I video record the image shown on the projector using the camera. So I expect to see see the images I presented right from the beginning on the video frames. What happens is when I then look at the acquired video frames, there are always between 9-12 frames that are there before the projector image shows up. I assume this is because there is some sort of a FIFO buffer on the grabber that keeps a history. I was wondering if there is a way to read this information or modify it through MATLAB? thanks for your help!
