FLVTO

FLVTO is a great and quick solution for downloading a video from YouTube, in any kind of quality and format, as well as downloading full playlists. You only need to search the video you want on YouTube, and then copy and paste the link in the upper window inside the application. To download the video here you must specify the format you want to use: MP3, AVI, MP4, FLV, MOV, WMV and WMA.

You will have to do the same process to download a complete playlist, but the playlist URL will be copied instead of the specific video. Next, you will see a list of all the videos included in the playlist before downloading, so that you can delete what you do not want.

All downloads will be stored in a common folder with the rest of the audio and video files. You can organize it in any way you want to create collections for your favorite artists and their music videos and songs.
