Abstract: A method of enabling media recording compatibility between client devices, comprising provisioning a first client device associated with a subscriber identifier with a household key also associated with the subscriber identifier, receiving a media content stream at the first client device, the media content stream having been encrypted by a content provider, decrypting the media content stream at the first client device, creating a recording with the first client device by digitally recording a portion of the media content stream, encrypting the recording with the household key at the first client device, saving the recording to a memory device, and loading the recording onto a second client device that has also been provisioned with the household key, the second client device also being associated with the subscriber identifier, such that the second client device uses the household key to decrypt and play back the recording.
