CL & log is below, but I was referring to what I see while stepping frame-by-frame. I see that, 
beginning with the 3rd frame, every 5th frame is combed. The combed frames are not decombed at all 
-- why would they be decombed? The input is progressive and yadif has nothing to do.

Would you like to see some screen shots?

ffmpeg -i "M:\Test Videos\23.976p.mkv" -filter_complex
