Exact smae issue here on an intel i3-3220 with intel hd2500 graphics.
When ill switch on dxva i have to disable deinterlacing (which also will be sets to dxva).
After that its smooth but not deinterlaced.

Also tried, which sadly not solved the issue:
 - sync playback with screen        off
 - change refresh rate                 off
 - Disable DXVA and use software rendering solved the issue, but the cpu load is very high on some HD channels -> fan is going wild. So no soltion.
 - advancedsettings.xml:
 
 <advancedsettings>
  <video>
    <forcedxvarenderer>false</forcedxvarenderer>
  </video>
</advancedsettings>

With the last change in advancedsettings.xml, the video of livetv is not jerky but also not deinterlaced, but the video setting is @dxva !?

Any hints about the issue?

Update!
I have solved the issue. It was the plugin "script.kodi.hue.ambilight" which causes the issues. 
After Deactivating the plugin all was fine.
Sorry for hijacking this thread!
