TubeQueue (Portable) v1.6

TubeQueue is a high quality freeware YouTube video downloader and converter.

It is different from similar programs in that it utilizes the concept of a "queue", or a list of videos which you define to receive a particular conversion action. For example, you could search YouTube from within the program and earmark three football videos as needing to be converted to MP4 for your iPod, earmark two music videos as needing to be converted to mp3 files in batch for listening purposes, and have one video that is simply downloaded as a flv file (for whatever reason). Once you've created however many queues you want to process in a particular session, you simply press a button and the program takes care of the rest.

Important note: You must run the program as Adminstrator in Vista (right click on the icon, and press "Run as Adminstrator").
