That fixed it thanks. Is D3D11 or copy back better? I think I have enough headroom for either now?By the looks of it, this is an interlaced HD DVD playing back at 29.969. That's normal for some content, like concerts, documentaries, etc. Looks also like you now have the LAV video decoder set to D3D11 native (at least for VC-1 and HEVC, going by your screenshots). That disables de-interlacing in madVR. Uncheck VC-1 and you should be set.
