Trying to get this idea rolling early, before anyone needs it.
As I understand it, when you are running IMG 1.9 and have an external drive connected to your DVR, the recordings on that drive are encrypted so they can only be read by the DVR the drive was first connected to. While I wish this weren't the case, I understand that it has to be, since the content providers are, as always, frightened of technology.
Since the external drive is used first for recordings once connected, people are going to have terrabytes of content stored on them, and if their DVR dies, they'll be completely inaccessible.
Why not create a way to transfer the encryption code from one DVR to another so that the external drive remains usable if the DVR is replaced? It could be a backend process where the new DVR is only sent the old DVR's code once the old DVR has been returned to VZ, which should be enough to keep content providers satisfied -- I'm sure you can work out the tech issues required and whether it needs to be done manually when the box is handed in, or if there's some other way -- but the point is to get this ball rolling so it's there when and if we need it.
