On fire tv 3 I do not have an option of Yadif deinterlacing in the onscreen menu when I choose to do software decoding for mpeg2 480i. Only Deinterlace or Deinterlace(half), or Off. Also any upscaler other than Bilinear or Nearest neighbor results in blurry picture. 
But the picture quality is good and smooth with Deinterlace and Bilinear scaling so I am not complaining.:-)
