It has almost become impossible to track the millions of Firefox extensions, bookmarklets and software utilities that let you save and download video clips from sites like MySpace, Google Video or Youtube.
Adding to the list is another free software called iTube with a simple and minimal interface - it downloads the video from internet (in flv), converts them to iPod format (mp4) and finally exports that to iTunes playlist from where your iPod can pick it up during the next sync.
iTube, brainchild of Benjamin Strah, is a neat software and does everything for you in the background. Can be used for downloading videos from Youtube, Myspace, Metacafe or even Blip.tv# and transferring them to the iPod.
While Google Video is also supported by iTube, that may not be very useful as Google Video lets you directly download video clips for the iPod or PSP.
