ADV7842 Color Accurcy

ADV7842 decoder and sending it YPbPr color bars via Sencore generator.  I am seeing some interesting things when looking at the output on a vector scope.


The lines between the color targets have a curved shape instead of linear.  Also when seding the bars at a 30Hz refresh rate there is a weird jog going back to the center point and may black bar is a purplish color.


What ADV7842 registers should I be looking at to remedy / improve these 2 issues?


My vector scope images are too large to attach to this thread.  They can be sent via e-mail if desired.
