ADV7842 and 480/576i with Component or HDMI inputs

I'm trying to send the output from an ADV7842 into the video input port of another processor. Using the SD inputs (e.g. composite) I can successfully transfer PAL and NTSC signals.

However, if I input 480i or 576i via Component YPbPr input, I cannot get correct video capture on the other processor.


Can you advise as to what settings I should use for PRIM_MODE and VID_STD in these cases? The documentation suggests that I should switch PRIM_MODE to b0000 (SDP), but if I do this won't I lose the ability to detect the other formats on the Component input?


Also, I think I will have similar issues when I put in 1440x576i and 1440x480i via HDMI inputs. In these cases, I still need 720x480 and 720x576 to be passed on to the next processor. Can you advise how to do this?
