You are not alone. I'm also seeing the deinterlacing problem in v18 under Windows 10 on two different PCs with both NVidia cards. It works fine on v17.6 but in v18 it spams the log with many errors like:

Code:

Debug Print: DXVA::CProcessorHD::InitProcessor: supported deinterlace methods: blend:yes, bob:yes, adaptive:yes, mocomp:no.
Exception thrown at 0x75CFDDC2 in kodi.exe: Microsoft C++ exception: _com_error at memory location 0x1483F1F8.
Debug Print: CWinRenderer::UpdateVideoFilter: chosen scaling method 1 is not supported by renderer
Debug Print: CRenderBuffer::GetResource: unable to open d3d11va resource.
Debug Print: DXVA::CProcessorHD::GetInputView: cannot create processor input view.
Debug Print: DXVA::CProcessorHD::Render: incomplete views set.
Debug Print: CDVDVideoCodecFFmpeg::CDropControl: calculated diff time: 40000
Debug Print: CRenderBuffer::GetResource: unable to open d3d11va resource.
Debug Print: DXVA::CProcessorHD::GetInputView: cannot create processor input view.
Debug Print: DXVA::CProcessorHD::Render: incomplete views set.
Debug Print: CRenderBuffer::GetResource: unable to open d3d11va resource.

I'm using the MediaPortal PVR addon, but the same problem is also visible via direct playback of a recording in the Video section.
