I received my S3 a couple of days ago and scheduled an appointment today for CableCard installation from Charter Communications (Long Beach, Ca). The installer called me to ask what kind of TV the cards were to be installed in and I told him that it was a TiVo... he told me that TiVos were not supported. They only supported TVs. I convinced him to still come and "indulge" me. His supervisor called me and gave me the same story... I told him that I wanted them to come anyway. So they show up and install the cards and they cannot acquire channels. I told him to leave the cards and I would troubleshoot myself. Next I called TiVo, they indicated that the cards are not set up properly. So I called Charter back and talked with a woman named Sophia. After spending about an hour on hold, she basically came back and said that the cards WERE set up properly and if I had a CableCard TV, they would prove it to me. The story they give is that the problem is with the TiVo and since TiVo was proprietary and they can't test it to make sure that the problem isn't the TiVo. So now it has turned into a Charter blaming TiVo and TiVo blaming Charter. Any ideas? Could this be Charter not wanting ts customers to use third party DVRs? Anyone else experience problems with Charter?
