7. D925 -> composite -> SVHS deck "passthru" -> s-video -> BT878:

This JVC prosumer SVHS deck apparently features "a Y/C filtering technique incorporated under license from Faroudja Laboratories Inc.". Sounds good, and although it's much better than the results from using the cap card's built-in comb filter, the y/c separation is no better than the comb filter built into the LD player. Dot crawl is about the same or worse, and the rainbows are much more noticeable at the top and bottom of the frequency bar.
However, luma transitions seem to be improved (less ringing/overshoot visible, but the diagonal black edge of the circle has picked up a halo.
