Hi, Over the last few flights, I've had some of the video file go missing. I can reproduce the problem easily: 1. Press video record 2. Take off 3. Film for a few minutes 4. Land 5. Press stop video record 6. Repeat 1 - 5 7. Power down the inspire When I mount the sd card in a tablet or PC, the first video is not there. The first file is DJI_0001.MOV and there's no break in numbering for the following files, even still photos. I thought I was going mad so last night I had a friend stand next to me and make sure I pressed start and stop recording, she watched the video time go to 8 minutes 43 seconds. She also confirmed that I powered down correctly. I've tried 4 different sd cards, made by two manufacturers. The firmware is latest (1.2.1.06). The first video is always missing, I've not checked to see if any other files are missing. Any ideas would be most gratefully received.
