When downloading videos from the Internet, you may run into a file type known as ISO. These files are not videos but contain the full information of a DVD disc for convenient burning. If you have downloaded a DVD movie that is an ISO file, there are two ways to watch the video contained inside of the file. You can either burn it to a DVD-R disc or install a third-party program that will allow you to open the ISO file and watch the video contained inside. Writer Bio
