I updated to the latest firmware a few days ago and haven't had a chance to test it out. I went out today and recorded a 2.7K video using a 64GB Class 10 card that I had been using all along on the mini. I came in and took the card out and put in in my Desktop PC. The file showed up on file explorer and I tried to open using VLC and Windows Movie Player. Nothing. In file explorer it shows up as a 2GB+ video file , but when I look at the file details everything is blank (no bit rate, pixel dimensions, etc). I reformatted the card on my PC and then reformatted in the Mini and tried again, SAME RESULT. It appears that the file is somehow corrupted and I don't know why. I took a photo on the same card and it showed up fine. Due to the firmware update?? Any ideas or suggestions?
