I replaced my TiVo HD with a Premiere last week. I went to a Cox store last Friday to exchange my two single stream cards for a multi stream card. I brought the tuning adapter just in case. They did swap out the tuning adapter and gave me a multi stream cable card. After setting it up and calling Cox to pair everything, the tuning adapter was blinking for an hour. I called Cox back and they resent the info to the tuning adapter and scheduled a service appointment just in case. An hour later of it still blinking, I called Cox again and the light went solid after they refreshed the tuning adapter. Unfortunately, every channel besides 1002-1026 then had a black screen with a TiVo message saying that I was not authorized to view this channel and to contact my cable provider. When I unplugged the tuning adapter, I got 1002-1026, but also got the standard SD channels. The Cox tech resent a signal and the same thing happened when I hooked up the tuning adapter. The full program schedule is on my TiVo. Restarting the TiVo and tuning adapter did not resolve it. On Sunday, a service tech came out and swapped out the tuning adapter. The same thing happened. He said he did everything by the books, but did not have another tuning adapter or cable card and scheduled another service appointment for me. Since there was still time before the Cox store closed, I went to see if I could swap the tuning adapter and cable card so I did not have to wait three days for the service appointment. I explained the situation and the guy said that the tech did not 'synch' the tuning adapter and cable card to the TiVo and to tell the tech to do that and it would be fixed. He would hook up his machine and synch it. When the tech came out yesterday, I told him exactly what the guy in the store said and he said his equipment can only tell the signal strength to see if that is an issue. He then called in a refresh without any success. He did not have a replacement tuning adapter or cable card and scheduled another service appointment for me for tomorrow. I plan on swapping out the tuning adapter and cable card this afternoon at the Cox store and have them make sure the tech that comes has several tuning adapters and cable cards. Has anyone had a similar situation? Anything I can try or suggest to the tech that comes out? Anything I can ask support when I call them? Any information would be greatly appreciated.
