ADV7180/ADV7179 output is not clear

Hello there,

I am using the decoder adv7180 and the encoder adv7179 in order to pass through the fpga the video.

I set the registers as follow:

0x00, 0x04, 0x17, 0x31, 0x3D, 0x3e, 0x3F, 0x0E, 0x55, 0x0E

0x04, 0x57, 0x41, 0x02, 0xf2, 0x6a, 0xa0, 0x80, 0x81, 0x00

for adv7180 and

0x00, 0x01, 0x02, 0x03, 0x04, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D

0x05, 0x10, 0x10, 0x00, 0x00, 0x02, 0x00, 0xCB, 0x8A, 0x09, 0x2A, 0x00

for adv7179.

The image i am getting is not clear..there are some shadows lets say..

I am not sure if the problem concern adv7179 or adv7180. The color bars working fine, but the free run mode of adv7180 doesn't work. Instead of blue i am getting grey..

Any help would be appreciated.

I am attaching a screenshot as well.
