And I thought just getting an M card for my new Premiere would be a simple process.... So today, charter showed up to install the card. Initially he installed the card only.....HD channels worked. Then he hooked up a tuner( which I didn't think he needed)...this allowed 1 or 2 of the movie channels to come in....Then he screwed around outside (which I now realized messed up the reception for another room).... and finally he removed the tuner, saying that only the m card was needed. Then finally he bailed, stating that someone else would have to come out at a later date. My questions are.... The VoD service that came with the HD box I was previously using (free HBO on demand/NBC/ABC etc...)... Will that not work with the Premiere and the Card only? Can "too Strong" of a recption from the cable line mess up your M card (thats what the Charter genius seemed to think). He removed my booster.
