I have a problem that I need to correct quickly. I have 2 Hs both with the same updated firmware all the way around. Also performed new calibrations. All systems seem to function correctly except for when I'm shooting Videos. During several flights it looks like I'm recording a video just fine but when I return to the office and try to view the file on my pc it shows there is a mp4 file there but when I open it I get the dreaded white text on the blue screen and the dreaded complete shutdown of the pc. I have many good videos taken with the camera a while ago but nothing as of late. Tried 2 different pc's with the same result so I feel it isn't a pc issue. Unless it's an issue with the software update I have no idea where to look to solve the problem. Any suggestions will be appreciated. I need to get it corrected as soon as possible. Appreciate your assistance.
