@Milhouse: any way to have an option to disable 3D-FP output alltogether for devices that don't play along well, so it reverts back to the "old" behavior of just outputting SBS or TAB without any frame packing? I think this problem will only ever get really resolved for output devices that support the full range of 3D resolutions and frame rates, like brand new 3D TVs and the like. My projector isn't just capable of receiving a full 1080p/60Hz FP video stream, only:

Have you disabled full frame 3D modes in video/acceleration settings?

Yes, I'm on #0619:

No hdmi_force_edid_3d=1 in config.txt
Video -> Acceleration -> OMXPlayer = off
Video -> Acceleration -> MMAL = on
Video -> Acceleration -> Support MVC video (full frame 3D) = off
Video -> Acceleration -> Use Full HD HDMI modes for 3D = grayed out and off

Filenames are:
R.I.P.D.3D.2013.1080p.BluRay.3D.HSBS.DTS.x264.mkv
R.I.P.D.3D.2013.1080p.BluRay.3D.HTAB.DTS.x264.mkv

Both files are 1920x1080@24fps with SBS/TAB directly encoded in the video. On start, Kodi asks for preferred 3D mode, no matter what I choose, I get the video in 2D (so it actually takes one half and stretches to fit the whole screen), and the GUI appears in SBS/TAB accordingly to the selection. Very frustrating.

Could it be as simple as the filename having 3d twice and Kodi is only reading the first instance of 3d?
