It was mandated that their STBs and DVRs use separable security and the only viable separable security that was ready was CableCARD. Their is no mandate specifically about M-cards, though many have gone with them because it will cost less for them to offer a DVR with 1 M-Card vs a DVR with 2 S-Cards.
I called Charter and asked for an M card, and a subcontracter brought out an S card and had no idea on how to install and activate it. But a second call had a Charter emp at my house with an M card and it works great. Whole thing from first call to my M card working was about 1 week.
