I think there's an issue with the Black levels and contrast while playing videos with SKYBOX VR 0.2.0, at least on the Oculus Rift version.
What am I talking about/how can you test it?
Take for instance: http://pd-media.zdf.de/360/zdf/terrax/vulkane/2015-11-11-2048x1024-H.264-AAC-FaberCourtial_de_3D_vulkan-pano_High_ab.mp4 since it has a lot of cuts to (almost complete) black between scenes and you can see clearly what I'm trying to say.
Play it in some different players like DeoVR from the Oculus Store or: http://badoinkvr.com/desktopplayer/installer/ which works per Drag&Drop.
Between the first time the volcano disappears and the temple scene starts 39 seconds in and after that at 1:08 when the birds start flying, then again 2 minutes in after the volcano erupts the screen goes (almost completely) black (as it should be).
Then play the same video in SKYBOX VR 0.2.0 on the Oculus Rift. The screen remains lit up in a muddy greyish tone.
That's not the only issue, since that alone wouldn't be a huge problem, but I think the video playback for all files is generally brighter than it should be, the colors are a bit off/less lively and the overall contrast suffers.
