   I just tried a .ts file I happened to have handy, with the ffprobe command   
   (part of the FFmpeg suite). Changing the extension to .mp4 made no   
   difference, it was still able to show a summary of the streams (audio and   
   video) in the file either way.   
      
   Moral: I wouldn’t trust Microsoft’s attempts at multimedia handling as far   
   as I can throw them. Stick to something tried and true and developed by   
   acknowledged experts, like FFmpeg.
