"Microsoft reserves the right to update your device anytime it is plugged in."
In previous updates, Microsoft has even removed significant features in its software updates. That quote from the EULA is why you can't call this a warranty issue.
Does anyone know of an automated interface that will update the DRM rights of Zune content if they expire? I am a subsribed user and am using Media Center. Everything is fine until the DRM expires. The only way I know to renew the DRM is to maually find the song and play it using the Zune PC player...Media Center offers no integration other than posting a message...Not very useful
