Hi, it turns out that the error message is a false popup. I ran some experiments with Files that got the Cannot Decode message, and when you hit Yes to Continue, Playing, the VR video plays fine without a problem. Not sure what causes the condition where the error message pops up, but when it does, Continue Playing will play it without a problem regardless of what SkyBox is saying. The error condition is consistent on the Files affected and will continue to pop up, while others unaffected will simply play as normal.
