GetFLV is an all-in-one program that lets you do different things with video files in FLV format like play, edit, and download them from the most popular video storage websites.
GetFLV divides its interface in various sections that correspond to the various things you can do: browser, download manager, converter of FLV to other video file format and vice versa, audio extractor, and file repairer.
The browser will allow you to search the web for the video you want to download. Thus, you can use it to access YouTube, Metacafe, Hulu, or DailyMotion, and download your favorite videos.
The file converter is divided in two sections—one for converting normal video to FLV video and another for converting a FLV file format video into another format. Among these formats are the most popular: MP4, AVI, WMV, 3GP, MPG, and MOV classified in different profiles: iPod, PSP, iPhone, Zune, Mobile, etc.
These tools perfectly complement an audio extractor that converts your videos into MP3, WMA, AAC, WAV, or AC3 files, and a FLV file repairer, which will help correct errors in your videos such as incorrect information about the duration, for example.

The aTube Cacher is the same and free. Only you have to put the download link to download the videos. But it's free, after all, it's what matters.
Download any YouTube video very quickly ... Now I have all the Eurovision videos on my computer (L) Perhaps the biggest drawback is that it is a trial version :(
