Does Verizon FIOS have MCards?

I have Verizon FIOS. My TIVO HD box just died and I purchased a new Roamio Plus that will prevent me from using the old SCards. Turns out I need a new cablecard just to watch TV. The Verizon rep that I am chatting with says that they only have one type of "cablecard". The web site does not say anything about recording multiple channels at the same time. If I order a new one will it be an MCard?
