if i'm not mistaken, dcf file is a copyright protected and locked file, the content is DRM promoted and will require DRM activation. in order to make them work on your mobilephone, click on the protected file to start the DRM activation. the phone will make a connection to the DRM server and open the WAP browser, when the DRM server authenticates your phone it will send an activation message to your phone and thus unlocked the content.

the above explanation is taken from here
