SUPER is a video converter that can convert pretty much any multimedia-file to any multimedia-format.
It got lots of options so you can get the file in the format you wanted but it’s still very easy to use. You can also batch convert files.
With Real Alternative you’ll be able to play RealPlayer-files without having to install the RealPlayer application. Personally I don’t like that you have to install a new media player just because some files is in another format. What Real Alternative does is to add support for RealPlayer/RealMedia files in your default media player.
