Run through the video router and it's fine. Some variablility in the black level between inputs. Won't matter as within reason the absolute DC level of a video signal is ignored by all video inputs. There's some kind of clamp or DC restorer on each output that may be getting things wrong. Not sure it's worth tracing.
More worrying are a number of bead tantalums. I'm tempted to just replace the lot as an insurance. 2x 22uF per output channel and 2x 4.7uF per regulator. The audio router also has tants for its regulators. For the sake of 10x 4.7u (I'd use 10u as I've loads of them) and 8x 22u it's probably worth the effort.
