An electronic storage device has a segment of digital video content recorded thereon as a data structure with a first set of data packets encrypted under a first encryption process and a second set of data packets encrypted under a second encryption process. The first set of video data packets and the second set of video data packets, when unencrypted, represent duplicate copies of the same video information. A third set of data packets contains unencrypted video data that is contextually contiguous to the first set of data packets and the second set of data packets. The first and third set of data packets represents all video content in the segment of digital video content as does the second and third set of data packets.
