I've been through a few cox phone techs now and no one knows how to fix this. Last tech seems to think it's an account issue. He has checked and made sure everything is cabled properly and even tried Tivo in a different location which has a cablebox. I've had a total of 3 cablecards 5 tuning adapters, 3 service calls, endless phone calls, and 2 tivos, I don't think there is anything else I can do on my side. Each tech has spent over three hours at my home trying to resolve this issue with no resolve. I am unable to get any of my tier channels, my premium channels or Cox on Demand. Please help me find someone who knows what they're doing.
Could be a issue with the upstream. It isn't needed much for TV service except for things like guide, OnDemand, and SDV, which is what the TA is for. I know there is a way to look at the upstream signal levels using the Tivo diagnostic menu's, but I don't know it off the top of my head. It should be below 54dB if you can find it. Hopefully someone with more Tivo experience will be more help.
the Motorola tuning adapter is needed it handles channel mapping instead of the cable card
AFAIK the cable card still does tuning, the tuning adapter handles the negotiation of the SDV system. As per moderator Becky here. So yea, you need a TA, but you can still get non SDV channels without one. I think the confusion comes from the similarity to the term digital tuner adapter(DTA) which is for digital>analog conversion. THAT does have a tuner, but a TA does not.
not on Motorola systems with tuning adapters? don't believe me un plug the adapter from the TiVo and see how many channels you can get
