Ares Tube is a multi-video downloader that comes with a built-in browser and allows you to save clips from YouTube, Google Video, MySpace, Blip TV, DailyMotion, Metacafe and many more sites that support FLV files.
Ares Tube automatically converts to IPOD, MP4 and MPEG so you can watch films on your iPod or external device. Alternatively, you can export downloaded videos automatically to iTunes. Simply surf to YouTube and Ares Tube will automatically prompt you to convert and import the file directly into iTunes.
When you connect your iPod , Ares Tube will automatically prompt you whether you want to transfer your converted files to your device. Note, however, that you'll have to install the .NET framework to use it, although if it's not installed the first time you use Ares Tube, you will be redirected to it.
Ares Tube is a great way to download FLV files from multiple sites without having to worry about which particular one it is.
