    What determines the type of encryption used by a CableCARD? Is this something that's locked in at the factory or is it something that can be selected by the cableco when configuring?

    I've seen CableCARD Conditional Access screens with
    Encryption: DES
    and
    Encryption:C CSA

    Can any given card be configured for DES or C CSA or is this something that's locked in at manufacture?

    What was the manufacturer of each one? I would venture a guess that one was a Motorola and one was a Cisco/Scientific Atlanta

    Both are Motorola MediaCipher M-Cards. Externally, they appear identical.

    So, no one knows whether a card configured for CSA can be switched to DES or vice-versa? I'd have thought it was part of the firmware, but maybe the decoder itself is a dedicated chip in the card. That would make sense.

    I have seven M-cards that were pulls from Cisco and Scientific Atlanta STBs but the cards themselves are Motorola MediaCipher and are for CSA decryption. I bought them hoping to save myself the cost of multiple card rentals each month but, while my cable provider uses Moto MediaCipher M-cards, they use DES encryption so these cards are probably useless to me.

    You generally cannot use purchased CableCards. Almost all cable companies will require you to use a cable card they provide.

    I did some digging and it appears CSA is used on DVB systems--mostly Europe.

    Do not attempt to escape the control of Big Brother. As punishment he may require you to use a Tuning Adapter!

    Unfortunately the authors of the Geneva Conventions never foresaw the possibility of anything as inhumane as TAs.
