I'm in the middle of an email exchange with Cox Fairfax customer service. It started with a *****-letter I sent them about their planned increase of CableCard rental rate from $1.99/month to $4.50/month. See this thread for more details (they have since decided not to change the rate after all). However, I also mentioned the fact that Cox NoVa persists in charging two digital gateway fees in addition to the two rental charge for two CableCards, even if both cards are installed in a single Tivo. The CSR pointed this out as "misinformation," and said that Cox charges only one digital gateway fee if two CableCards are installed into a single Tivo Series3 or TivoHD device. All you have to do is tell the sales rep that both cards are for an HD Tivo when you set up the appointment. This is news to me. I've called their customer service line twice to get estimates on the cost of upgrading to digital service for my Series3 (I'm cable+OTA at the moment). Both times I was informed that I would be charged two digital gateway fees. And I have yet to find a single poster from NoVa in the Cox CableCards thread who is paying only one digital gateway. So, Cox Fairfax customers: what are you paying for CableCard service to your Series3 or TivoHD?
