I'm trying to run a retro game console (SNES) through the ADV7180, but unfortunately I'm having an issue where the video is "rolling" presumably due to a vsync issue.
You can see a video here: ADV7180 Rolling - YouTube
The SNES is hooked up via composite and it outputs 240p.
I've read through the datasheet and tried setting various registers which seem interesting but nothing has any effect on the vertical rolling at all.
Is this just not possible because the SNES has a non-standard output format, or am I missing something?
Any guidance would be most appreciated.
