Comment Got mine working through Charter no issues. (Score 1) 178
I have had Tivo since the day it came out, was one of the first to have mcard and the cable tuner when that came as well. I never had an issue with it. The Charter guy showed up, plugged the card in, called a number, read off a string of numbers and letters, worked just fine. That was almost 10 years ago. When the cable tuner came out, same thing, guy shows up, plugs it in, doesn't even need to call anyone. Leaves literally 2 minutes later. Everything has worked fine since.
Not sure why you're having any issues. While they might have different area techs, we all connect to the same provider at the other end. Just my 2 cents and experiences.
