Need some help. I was recording a video on my 9850 when the battery died. After charging I could not find the video file. I connected to the computer and found the file, but it had a mp4.lock extension instead of the normal .mp4. I changed the file name to .mp4, so it shows as a video file, but when I try to play it gives me an error "unsupported format". Any thoughts?
