I recently got my S7 and Gear VR. Loaded a couple .mp4's and an .mp4 3D movie, too, onto the internal SD card. All worked really NICE in the Oculus Theater or whatever it's called. Coraline was the 3D movie and the 3D was pretty good, I'd say about 6 on a scale of 1-10. But it was really crowded on that internal memory card! So I purchased a Samsung 128GB card for the external card tray. Deleted the original movies and created a "Movies" and "Movies/3D" folder on the new 128GB card. Moved the original test movies plus a couple more 3D movies (these 3D movies to the "3D" folder as originally done). Now, in the Oculus Theater, under "My Movies" it sees NOTHING, reminding me to move some movies to my "Movies" folder. Aargh. Other Apps on my S7 see these files just fine: Astro File manager sees the folder structure intact. I played one .mp4 directly with the "HD Video Player" App. Any ideas about why the Oculus software can't seem to see anything on the external SD card? Is there something I've overlooked, maybe some configuration thing the Gear VR needs, in order to access an external SD card?
