EVAL-ADV7842-7511 Noise Interference lines

Question

Hi, I have a EVAL-ADV7842-7511 Board which I'm using to decode CVBS signal from a Laserdisc player. 
 I have an issue where I'm seeing faint diagonal lines across the image. These are present on all of the input formats 10Bit, 24Bit and 36Bit and is also present on the s-video input. 
 It it looks almost like interference. I've tried multiple cables and players and all produce the same results. 
 Any idea what is causing this? 
 many thanks

I also had the problem of diagonal interference lines with the scripts. Turns out that the script didn't enable the anti aliasing filter. So I just had to enable them:
