Making slow progress. I'm pretty much down to one remaining problem. There are diagonal lines in the video that I suspect are caused by my video circuit. Phil is also working on a video inverter circuit for his set, but didn't mention the same issue, perhaps it's unique to my set. The lines are more noticeable on brighter scenes and are extremely difficult to film. Luckily while watching Daniel Tiger with my daughter this morning I found the perfect scene to show the problem.
