I guess in many markets Spectrum isn’t handling those DVRs. I think they are what was termed a “whole house” DVR, where you could access it from all your TVs. That is why the 6 tuners. I have run into a couple instances where with mine 2 recordings would be taking place at the same time, and the lack of a third tuner kept me from watching something else. And, then at other times, it sure acts like it has 3 tuners.
