EVAL-ADV7842-7511(P) picture quality problems

We are using the EVAL-ADV7842-7511 board and with the composite video capture there is some mild fake color capture during movement.  (we see rainbow colors during motion for things like stripes or checkered shaped objects on shirts, for example). 

Also, when observing still images for analog quality, there is some bleed through for black to white transitions creating something of a shadowing effect that should not be there.


1. What registers should I be modifiying to clean this type of disturbance up? 


2. What registers should I be modifying to clean up jagged edges where, when capturing images such as wires or objects that wrap around in non-straight lines it is not as smooth a transition? 

3. What can I do to improve the quality of still images?
