The High Frame and 3D stream manifests may all avaliabled only on the TV or the other hardware playback devices.
I will ask the dev to check it in future.
Well, sounds like it’s a matter of finding the right manifest, ditto for DTS:X support that seemingly comes with a lot of iMAX-enhanced movies ;)
In StreamFab 6233, DTS:X will be also supported in plan, but for some playback problem, the option is removed before releasing the new version.
But Atmos audio quality should be enough for downloaded.
