ADV7842 AV Codes Non Standard VGA resolutions

Hi

 

A while ago, with the help of some folks at analog devices, I managed to display non standard VGA resolutions. This means that if someone has plugged in a VGA signal into ADV7842 with the resolution is eg. 720p 60Hz (which is not in the list of predefined resolutions for VGA) I had to shift DE start and DE end to get the correct video.

 

Now I have to also insert AV codes. My question is what do no I need to do to make sure that the AV codes are inserted correctly when I am in the mode described above (Auto Graphics mode).  

 

Thanks
