Flipping Normals, Maintaining Text Orientation, 360 Player

I'm working on a GearVR + Unity 360 video player, but am having trouble with in-video text: text appears backwards. My current prototype is a hack on the Oculus Sample Framework and the 360 videos will play on GearVR.

Attempt #1
I put the video texture on a sphere and attached a FlipNormals script. The text was backwards, which makes sense to me.

Attempt #2
I made an inward-facing sphere in Blender and exported to Unity so that I did not need the FlipNormals script - text is still...
