    Because the model is working for other provider two years and gather good response from ppl who are lost their DVR by failures and used EHD.

    How do you know that the Encrypted Special Unique Key is not a Hexadecimal Key Data Field with the RID # contained within that unique key field converted to hexadecimal code???

    Because your proposed sequence of checking RID doesn't have any real proof. But it flawed to nullifying by the fact of accepting other DVR the drive and other DVR actually support all data exclude recordings.

    Adding to that: show me those SW manager who will approve your algo for encryption data based on known key.

    Well, if your receiver breaks down it is not like you can get the recordings off the internal drive anyway, so all you are doing is depriving yourself of a larger recording capacity. ;)

    We did this encryption all the time when I worked at 2 of the largest banks in America and the second largest credit card processing company in the world.

    It is very easy to do and no big deal as to what you place in the field prior to encryption.

    DTCP Rules could care less about your replacing a hard drive in your DVR. That is between you and your DVR Provider. However it does care about sharing recordings with others as not provided in the DTCP Rules so it does place certain burdens on those such as Directv to disallow recordings being viewed by those that don't have that specified privilege.

    So Directv encodes the recordings with RID # Information so it can compare that info with the RID # of the DVR to either Allow or Disallow the Playback of that particular recording. So yes you can view the recordings listed but you can not play it back on any DVR except the one that has a Matching RID #.

    Very simple to code!!! And very simple to change if Directv decides to do so.

    I would assume in your time that encryption was selected from well proven algos like 3DES or AES or <...>.
    The sat companies using proprietary encryption with very rare exception.
    And back to facts: it is play encrypted stream. Not your suggested "Allow or Disallow the Playback of that particular recording" test.
    But because the DVR key is different, nothing decrypting.

    Let me ask you directly - are you just posting your very own speculation ? Regardless to unknown to you knowledge how the DVR working ?

    Yes I am posting my own speculation about how the process works.

    And how do you hypothesize that the DVR knows whether a particular recording has been recorded by that DVR or another DVR if the recording does not contain some kind of information about the particular DVR that recorded it?

    Can you answer that simple question?

    One day estata maybe become "supported" but right now it's just something that someone can choose to use or not. If they decide to start charging a fee for it like Dish does then I would suspect they would make it more account friendly. Right now it's use at your own risk and don't call us about it.

    Also they could use one, or a combination, of hundreds of different numbers in the box. While using the account number would work we have no idea if the STB's even know what the account number is. Chances are they do not and directv does not have a unified number available for this task. I'm sure if it already existed and they could generate a revenue stream off of it they would have by now. With the advent of the future in HR24 type technology I wouldn't hold my breath for something like this to happen. As the whole home situation comes closer to pass the need for this is slowly going away.

    Unless of course that whole home receiver goes out and someone wants to shift the external HDD from that to a replacement. It's still a possibility at least.

    True but my speculation is they will have a unique identifier in these systems to allow something like this and that they will have a supported service for this with the new units unless they do something like a 1.5-2gb drive to start with.

    I would say if we get some more information and the HR24 comes with USB3.0 or an external e-sata we'll know for sure if they plan on supporting it.

    Broadcom doesn't support USB 3.0 in STB chips.

    Only after I'll see a picture of the chip inside HR24. :)

    It sure has fallen on deaf ears, while they seem to be busily and enthusiastically developing other far less useful things like TV Apps so that maybe we will be able to Twitter on our DirecTV box at the speed of molasses instead of providing their customers with a way to keep from losing their valued recordings.
