Hi,

I have HD video working on my ADV7511 with the following register settings, but I am not getting video out when my source is set to 480i/525i. Can anyone confirm that the following register settings are sufficient to pass SD video or are there additional registers that need to be set for SD? My source outputs a 20 bit 422 YCrCb signal, formatted according to style 3 in the adv7511 datasheet.
