NO, you get ALL the Channels. Maybe he meant that you only get the main channel for each premium channel in HD, which is true. Did you manage to get an M-Card? Or at least did you request it? Don't be surprised if you request an M-Card and you get an S-Cards. Most Installers are clueless about CableCards. If you run into any problems you should contact Jose Negron (email@example.com) in the IT department. He's the man! Good luck!
