I just got off the phone with my cable company. They say the next time I can have a tech come to the house to install the two cable cards for my new Tivo HD is Mid september. I'd really like it to be done before then They said I can come to the local office and pick them up... can I install them though? And, if so, can anyone explain the process. Is it as easy as just plugging them both in, and calling them to have them INIT it? Thanks.
