If you're a power user, then I'm sure you've heard of AviSubtitler. This is an application that was designed for one purpose: Subtitling. It allows you to convert your favorite movies to subtitles so you can watch them anywhere in the world. It also helps you by giving you the ability to create your own subtitles. Now there's some applications that are able to make subtitles but only some can even come close to being able to make subtitles as good as the ones AviSubtitler has.
But what about the free download? Well there are actually two versions of this program. The "lite" version is completely free but the full version costs a minimal amount of $29.99. What this software does is it makes subtitles from DVD titles. Of course there are some people who have never tried it before and they just don't understand what it is. This is why there are FAQ's included with this program. You can look into them if you ever get stuck.
But let's say you've already downloaded this software and you're already familiar with it but you don't need to use it anymore. You can always restore it to a backup file and use it as a part of your backup routine. At times it's not safe to just get a whole new application if you have already downloaded it. So what you can do is just restore the backup file that was used previously with the software. And if you really feel like that, there are programs that let you do that.
