Can you play a dual-fisheye video from the USB stick, similar to how you can play the dual-fisheye videos directly from the THETA? I believe you need to manually perform the stitching with the official Ricoh application when put the video onto the USB stick, right? I could be wrong.
I may have missed it in the video, but you may want to make a bigger emphasis that the main advantage of using the USB cable is that you don't have to stitch the dual-fisheye video into equirectangular. I don't have access to a Playstation and I could be wrong about this.
Also, I think that the Playstation only works with the RICOH THETA in this way.
