I am having trouble w/ my S3 (with lifetime service) and installs of multistream CableCARDs. I have 3 cards and all seem to connect fine on my HD Tivo, providing both Host and Data ID so that I can relay them to Comcast. When I take these same CableCARDs and put them into my S3, I get an odd pairing error. Authorization Failure 1040. Host Certificate Invalid. Spent time w/ Tivo on chat and via phone and both agreed there was some type of hardware problem w/ my S3 because it was not providing a certificate to the CableCARDs. The solution was to replace my Tivo w/ a different box that that requires me to buy a refurb at a discounted rate AND have to transfer the lifetime sub for another $200. Good grief. Has anyone had this problem and figured out a fix/workaround? I just want the dang cards to allow me to pair. I've rebooted and checked the cable lines. I've cleaned the contacts on the S3, nothing solves it. I've had this working w/ CableCARDs as recently as 3 years ago before we shut off cable but we came back. So it did work at some point.
