I'm sharing this because the few Altice / Optimum customers still running Tivo are a dying breed and we're going to need to support each other.
I succeeded in getting Optimum to pair a new cable card this week but it was not easy. It require 9 different attempts. I know it was 9 because the last service rep told me she had read my file. So they do actually keep notes on your customer service calls. A couple of those were via Chat where I threatened to switch to FIOS if it wasn't resolved. (Some of those sessions were over an hour long.)
Three times, the call or chat ended with them saying that I needed to call a different number; twice, the number was Tivo customer support. One time it ended with them telling me that they don't have the tools to support a cable card.
What is really frustrating is that once I finally was speaking with a technician who had the proper instructions it was all resolved in 15 minutes. All she really needed was the Cable Card ID and Host iD and the right software tool in front of her. That person told me it was the first time they were doing this. All of the support reps. were women with strong accents who were obviously working from very simple scripts.
My problems started because HGTV started to freeze and pixelate. I thought I might fix it by re-seating the cable card. After I did that, the Tivo hard disk failed. After I fixed the hard disk, when I called Optimum to pair it , I was told I needed a new cable card. So maybe in the end my HGTV problem was an old cable card. I have heard that FIOS does provide better Tivo support, so if this happens again, I am making the switch.
