You can only play the files you purchase at BBC Shop using Microsoft Windows Media Player 10 and above because this is compatible with the Digital Rights Management (DRM) encrypted audio and video files that BBC Shop offers. Windows Media Player runs on Desktop PCs, Laptops and on some portable media players.
To transfer the files to a portable media player it must conform with the Microsoft ‘Plays for Sure’ standard. Look for the Microsoft Windows Media logo and 'Plays for Sure' logo on the box, or within the instructions for the player.
Unfortunately Apple Macs and iPods use an encoding format that is unique to Apple and the iPod. Therefore Apple Macs and the Apple iPod do not directly support transfer of files in the secure format downloaded from the BBC Shop.
