Hardware Acceleration

I am currently using Kodi 17.1 on Windows 10 with a Nvidia 1060 with up to date drivers.
When I set ‘Render Method’ to auto detect and switch on DVXA, and try to playback pre-recorded SDTV the picture is jerky.
If I leave Render Method to auto- detect it will not default to software decoding for SDTV.
I need to manually select ‘Render Method’ to software to achieve a smooth picture.
Is there any way I can resolve this?
