My Gopro Hero 3 Silver with new Sandisk Ultra 64GB Micro SD Class 10 is not recognized by media for playback, I can only see files on computer as an external drive. If I change the Micro SD card to the 2GB the media such as TV & playstation recognise the 2GD, but not the 64GB. The only thing I can spot the difference is on the format, the 2GB is MS-DOS (FAT16) the 64GB is ExFAT. What is wrong?
