After updating to the latest build, it's no longer switching my TV to 25hz when watching 25fps 1280x720 BBC iPlayer downloads but 1080p/50hz instead.

I thought that is what it is supposed to do, as of a couple of builds ago:

Build Higlights:
The 3D Switching patch has been updated, removing the change to pick the smallest multiple of framerate rather than largest, so now 25Hz/50Hz etc. behaviour is restored, albeit at the cost of slightly increased load. Many thanks Popcornmix.

I don't know about that as I'm not using 3D but I'd have thought it better to match the framerate of the material exactly, no? If it doesn't actually make any difference whatsoever though, then no worries
