Do they all get output as Frame Packed 1920x1080/24p (which is effectively 1920x2205/24p with 2 x 1920x1080 streams one above the other with 45 lines of blanking between the top and bottom formats) and retain their Full HD 3D resolution or are they converted to 1920x1080/24p HSBS (i.e. 960x540/24p for each eye with no blanking between each 2:1 squeezed eye feed) for output, effectively halving their resolution?
Doesn't the nVidia Shield not cope with 24p properly? So are the 3840x1080/24p movies replayed at 1920x1080/60p with 3:2 judder and halved horizontal resolution? I don't think the nVidia supports a Frame Packed Full HD 3D output does it? (The Pi and Pi 2 are unusual in doing so, outside of Intel Core i-series CPUs and dedicated nVidia and AMD GPUs?)
The other players output these files as HSBS or HTAB. This just means that there is actually no benefit to ripping the movies to full SBS/TAB. It looks like full SBS/TAB files are supported only on PC (Cyberlink PowerDVD, Stereoscopic Player etc., output is framepacked 3D).
For whatever reasons, RPi2 is unable to convert these files to HSBS/HTAB. It could be because of the hardware MVC decoding support, but I would have expected full TAB to work.
nVIDIA SATV does have proper 23.976 support on OTA 2.0 firmware.
