When I got home, and opened up the SD cards, I noticed that the expected video files were not there, but there were gigantic .RSV files instead. Upon investigation it turns out they are the files that Sony cameras create if there is some kind of power failure or the camera crashes. They will not natively play back as video files, however, unless they are converted. All the utilities I found on the web were paid, so I reached out to our guy to see if he had any thoughts. (2/9)
