Matt and I are looking into it by cross-checking both the old board/new board with both the old/new firmware. Could you also post a picture of the output from the older 3.1 design? I think it might be related to some of the gain settings. The ground plane is identical — the digital and analog power nets were actually pulled away from each other in the new design, which is what I think you’re seeing.
I have noticed a similar effect in the past with DVD sources, due to cross-talk between the ADV7280 oscillator and the video input, but fixed it early on with extra decoupling capacitors.
PS – image might be a little more pixelated because James-F was kind enough to help me figure out how to increase the luminance bandwidth on S-video. I guess we’d hoped that would be a good thing over a softer image 🙂
