Ever wonder about downloading YouTube videos onto your iPod? The problem is that YouTube (and most other video sharing sites) uses a Flash format, and your iPod needs a QuickTime format such as MP4. The solution is a piece of software that will assist with the video download, do the format conversion, and place the converted file in your iTunes folder for easy transfer to your iPod. Michael Arrington of TechCrunch recommends iTube for Windows or PodTube for Mac.
