For me, no. Doing so in the "Video Options Menu" (via playback OSD) had no effect whatsoever.

I would however still say that there is evidently some form of issue present. Setting the "Render Method" to "Auto" should automatically select the correct option based on installed hardware / driver support. So in my case it *should* be automatically be selecting DXVA render mode if Kodi is able to determine it's supported and available. Given I have to explicitly select DXVA mode to get it to work, this is evidently not the case at this point.

Looking at the EDIT2 in your previous post it seems that something is working at the end...I have to try also this way on my setup (besides the one I have described you before, i.e. acting on DXVA deinterlacing option through the OSD menu). Does your approach maintain the correct de-interlacing even when you change the TV channel?

I think that the only way to solve the issue is to debug the code while playing some TV content...but it is something that goes beyond my knowledge and that only a developer can do...Unfortunately it seems that there is a lack of resources to focus also on this issue. I just can not just imagine the first official release of Kodi 18 with this problem...taking into acocunt tha Kodi 17 is working without any deinterlacing issues. Can you also confirm this on your setup?
