I will assume that you are transferring your video files via Firewire. If you are, have a look in your Windows Device Manager under IEEE 1394 (left arrow down) and see what driver you are running. If you see this exact wording: 1394 OHCI Compliant Host Controller and nothing else, then you may have to change your IEEE port drive to the Legacy version so that your camera is recognized by the computer and/or editing software. The proper one should show this: 1394 OHCI Compliant Host Controller (Legacy)
Don’t mind the Win 8 / 8.1 header on the download page, I have used that driver on Win 10 version. Microsoft noticed this problem after Win 8 came out.
Your problem with this file may be viral or just plain hokey and/or bad compression. The file name looks like a file downloaded from a torrent, specifically an episode from Game of Thrones. I recognized it ’cause I keep cleaning my friends computers… If that is the case, delete the file(s). One should never trust a file from a torrent.
