One report says a full media card resulted in phone-recorded videos to get "almost" saved but as a corrupt file. No message was given about the full media card. When the corrupt video file was played, it caused your same error message. Kelly Carter
a media card that is removed, or partially removed during the saving of the file will cause this as well. you can attempt to transfer the files and play them on the PC. Odds are they will not because they are corrupt.
