ADV7181B How to Remove Black Lines at Top

I am using an ADV7181B with a PAL Camera which generates composite video but the first 24 lines from the camera are all black.  The camera also outputs 23 black lines at the bottom of the frame as well.  I believe the camera is trying to generate some sort of "Letter Box" format so that a "Wide Screen" image is embedded in a standard PAL frame.  My customer wants the image expanded to fill the entire frame.  Can the ADV7181B be made to do this?  If not, is there at least a way to skip over the first 24 lines?
