Ipod Touch Youtube Video Converter

Is there a free one? & Which is the best? & Do you also need a program to save Youtube on your computer or do you convert the videos directly from Youtube? & How long does it take the videos to be converted? I have Windows Xp.

do you want an app or a downloader/converter for pc so you can do it manually?

There is lots of firefox add-ons that can do what you wish
