Interesting. I get a different result with wrxtasy's build #3 - I get a TAB 3D image squeezed into the top half of a TAB bottom output. So I get two quarter height strips with video in them. This is only the case for a 3D MVC, I just get 2D with a 3D ISO (which plays in 3D fine on a Pi 2).

What settings do you have for 3D output in System Video or Video Playback?

TAB is signalled in the VSIF bit of the HDMI signal - there are different codes for frame packed, HSBS and HTAB.

That is odd; so, just tested on my secondary 3D display (BenQ W1070 PJ) and I get the same results w/3D MVC MKV & 3D ISO (just as w/my primary 3D PJ Epson 5025UB):

Also, should clarify, I did choose "Play with 3d mode" for 3D ISO even though my pic #7 above shows "Play main title" highlighted.

Reinstalled Build #3 and it works to a degree. If I Play with 3D Mode on the ISO I get proper TAB (the Pi 2 implementation detects the MVC stream or presence of 3D files on the Blu-ray and doesn't need this). Jumping forward 10 minutes crashed my box. Rebooted. Played the 3D ISO again and it was again OK. Switched to a 3D MVC MKV and it juddered like crazy (but in TAB mode)

Good work people. So 3D MVC playback on the AMLogic stuff is getting there, albeit with TAB rather than Frame Packed full-resolution output. On my 2160p Passive 3D display (which is 1080p resolution for 3D) I think I see the resolution loss in HSBS (960x1080) more than I do in HTAB (1920x540), so it may be the better of the two ? (And it's perfect for people with Passive 1080p 3D displays who only get 540p res anyway...)

Also - Kodi in general doesn't seem to know it is in 3D TAB mode - as the GUI is still rendered in 2D (for the top right playback info UI this is OKish as you get a 2:1 stretched UI in one eye)
