I had the HD die in my S3. I used dvrupgrade s/w to install a 1T Hitachi drive. TiVo boots up fine, but the cc are not decoding the scrambled channels. I called Time Warner and they sent the Hit signals and a full Initial. Signal, but the cc will not respond. Is it possible that the Tuning Adapter is blocking the cc from the Initial. Signals? I doubt TW ever anticipated a cc pairing to happen after a site has had a working TA in place. I asked the TW Tech. If we should remove the TA while we get the cc up and running, but she said "no". Any thoughts?
