Xilisoft iPod Magic Platinum is a tool that allows you to both make backup copies of the content of your iPod as well as rip CDs and DVDs so that you can copy songs and movies onto the device.
Everything is controlled from an interface that is significantly easier to use than iTunes. Managing your different multimedia files is a breeze.
The application doesn't have any trouble converting other video and audio files into those files supported by the iPod, something that really comes in handy when you want to put files that you've downloaded from sites like YouTube onto your device.
The program also gives you the ability to create and manage photo albums, so you can store tons of images in a folder on your iPod.
Xilisoft iPod Magic Platinum is a powerful iPod management tool. It's not perfect - it lacks a few key features - but it's definitely worth a try.
