A system and method provide for content to be downloaded by an information handling system (IHS) and written to an optical storage medium. The content is protected by a content protection system. The content on the storage medium may be decrypted and displayed by a playback device. An invalid credential is written to the storage medium, for example, after display of the content. The invalid credential restricts decryption of the content. Examples of credentials that may be invalidated by writing an invalid credential to the storage medium include any keys, usage rules, or other items required for the decryption of content, for example, under content scrambling system (CSS) or advanced access content system (AACS) content protection systems.
