TouchCopy will highlight songs that are protected by Digital Rights Management (DRM) with a lock icon. TouchCopy will still copy these files but you can only play them if you have the correct rights to do so. These are songs that you will have purchased on the iTunes music store.
Please ensure your computer is authorized with your iTunes music store account before transfering your music back into your iPod.
In iTunes select Store->Authorize Computer... from the menu. Then please use iTunes to re-sync your iPod.
TouchCopy cannot play video that has been purchased via the iTunes store. This is a technical restriction from Apple.
However, TouchCopy can still copy these files to your computer or to iTunes. Once they are there, you can use Quicktime or iTunes to view these movies.
