Here’s how you can tell if you just wasted alot of bandwidth by downloading a bogus movie file. Download a hex editor. Any free hex editor will do. Open file in the hex editor. Scroll to 1/4 the way past the beginning. You may notice multiple 00. Not a good sign. Scroll to 1/2. If the 00 continue without change all the way to the end of the file...well you can add. !
