Build #0713 introduces the delayed audio & video startup. interlace settings was set on auto. Changing these to off and restarting kodi allows this file to playback normally.

Code:

(New firmware with 1080i de-interlace; new kernel 4.1.2; bump to ffmpeg-2.7.1; BCM270x: Switch to firmware driver)

looks like you was onto something with it detecting it as interlaced

I have gone back up to build 914 done some playing.
With "Deinterlace Video" set to "Auto"
choosing any specific "Deinterlace Method" reults in normal playback
choosing "Auto Select" results in the delayed audio & video start
With "Deinterlace Video" set to "On"
choosing any specific "Deinterlace Method" reults in normal playback
choosing "Auto Select" results in playback not starting at all
