After 6 months of flying the mini I am all of a sudden (last 2 flights) having an issue with my video recording names. Previously the names would be "DJI_0098"... ,now I am getting those as well as ones labeled AQT{AE740417-F052-43E2-8EE8-9FBE88F11C45}. The strange named files will not automatically open, I choose MS Media player and I rcv. message saying format not recognized but they will still open. They are videos I recorded but I do not know why the names are different.
