ADV7180 - Vertical Sync Issue

I've put together a ADV7180 breakout board for a Freescale IMX6Q processor development kit. I'm able to bring in NTSC video into the system (through BT.656 bus) but it constantly rolls up the screen and occasionally stutters. Both the horizontal sync and color/image look good though. I'm also getting the following error: IPU_INT_STAT_5 = 0x00000001. This interrupt means there is new frame before end-of-frame error interrupt on IPU channel 0.

 

I've attached my schematic/layout files as well as a video of the behavior I'm seeing to this post. I'm new to video hardware and would appreciate any suggestions on where to look next. Thanks.
