Mike writes "As if the Zune wasn't already crippled and unpopular enough, now comes a story indicating that Microsoft may build a 'Copyright Cop' into every Zune. A future update of the software for Microsoft's portable media player will likely include a 'feature' that will block unauthorized copies of copyrighted videos from being played on it. The president of digital distribution for NBC, J. B. Perrette, said the plan is to create 'filtering technology that allows for playback of legitimately purchased content versus non-legitimately purchased content.' Of course there's no way to tell legitimate content that you create from 'non-legitimate' content, so this looks like just another nail in the coffin of the Zune." Update: 05/08 20:50 GMT by T : From Microsoft employee Cesar Menendez comes this categorical denial of any such filtering mechanism.
