As weird as this sounds, I was recording a video of the Blue Angels practicing using my smart phone & recording it by holding my smartphone "still" focused on my tower monitor. Once it was over, I clicked the video button to stop recording but it kept recording. I pushed it a few more times but it kept recording so I pushed the button to go to the desktop & it went to the desktop. After that I tried a few times to play it but it won't. I saved it to My Documents & tried playing it there but it still won't. I have recorded other videos same way & they've played fine. Any ideas? I even tried to change the properties from .MOV to VLC but still nothing I don't know if I can upload it here, but will try if need be.
