iFunia YouTube Converter is a video downloader and converter. It can download videos from YouTube.com in their original format, and there is a built-in video converter that allows you to convert those videos to an array of other formats. You can even use the converter for files you already have on your computer, but they have to be in the FLV format for the app to open them.
Graphically, this application consists of a single window which transforms depending on what feature you are using. By default, the downloader is shown. At the top of the screen, you will see four buttons: Add URL, Restart, Stop and Delete. If you are in the converter, you will see the files that you have added and a few more buttons, and one of them resembles a wheel or gear. That one lets you change the conversion settings. The converter has a very good output format support, and there are even conversion profiles for devices like the iPod, iPhone, and gaming consoles like the Xbox 360, Playstation 3, and PSP.
In my testing, I had no problems downloading videos and converting them. I was positively surprised when I saw that, by default, the highest-quality version was downloaded.
