Software to download all videos from a YouTube playlist?

Question

Could anyone recommend me any software which can help me download complete youtube playlists?

There's a lecture series thats only available on youtube, and I really want to download all of the videos at once to my pc. (Around 55).

Free Studio from DVDVideoSoft includes a Free YouTube Download component, which appears to work.

From the website:

Free YouTube Download. Download all possible YouTube videos to your computer:

• a single YouTube video;
• complete YouTube playlists and show lists;
• all video responses to a YouTube video;
• all videos of a selected YouTube user or a channel;
• all video from the user favorites.
