If you just want to download the youtube video in flv, there is an extension on Firefox to get the flv video http://www.downloadhelper.net/. Or there are sites to help you download and , if you want, convert the video for you.

Definitely MPEG Streamclip. It can download youtube videos and export them into almost any format, including just exporting the audio of a video. And It doesn't just do youtube videos, but also video and audio files from your drive.
