Sometimes it takes me a while to work things out.

Tonight it occurred to me that perhaps there were some user settings in MythTV 0.25 for hue that got screwed up.
I had never adjusted the video settings before because they were always right before.
Anyway, I found the hue setting was at zero, I set it to 50%, and video is working again at least as well as it was in 0.24
(still tearing, but that I'm sure is a driver issue).
