ADV7343 NTSC/PAL missing 1 pixel

I need help to understand why we consistently get 1 less pixel when outputting NTSC or PAL at each resolution we have tried?  When NTSC and PAL are set to 720 active pixels we only see 719 pixels on the screen.  When setting NTSC to 710 we only see 709 pixels.  When setting PAL to 702 we only see 701 pixels.  We are sending an image that has a single pixel border outline in white with a grey background.  When I reduce the image by 1 pixel I see the whole border. 

 

We have no issues when running RGB video in graphics mode.  We only have this issue in SD mode. 

 

Thanks,

Mike
