ADV8005 Eval SD encoder line fliker

hi,

I am using the eval ADV8005 to convert from 1024x768P60 to 576i.

I am using the following configuration:

The conversion is good but unfortunately the video is flickering, with PLL on and x16 oversampling the result is even worst.
How we can solve this problem?
