By accident, I just deleted some .MTS video files from my vacation to Yellowstone, but then used a program to get them all back. I got them all back, but a few of them won't open (they might be corrupted). I can open most of the files but some of them just won't open up or play. I also noticed that the file sizes are about the same, so I was wondering if there is some way to repair these files so that they would play. Any help would be greatly appreciated! Thanks!
