ADV7391 output

I'm sending a color bar image to the ADV7391, the problem is that the output to the TV is not synchronized to the start of frame.

When the PLL is off  i.e. Reg 0 bit 1 set to set to 1) the image is constant but not a complete color bar - image number 1, but when the PLL is on the color bar start position is changing for each operation - images 2 and 3 for example.

The digital input to the ADV is similar for each operation. 

How do i configure the ADV to show the correct image.

The ADV is configured to work at 720P 60HZ., it should sync on Embedded EAV/SAV codes

thanks

Yoni
