This my first time posting and I hope I've picked the correct forum to post this. I receive my cable through an ethernet cord. This cord is then connected to a cable box. I have currently have a Series 2 tivo and it works great. It is connected by attaching IR blasters to the cable box. My cable company recently announced that it will be offering High Def content next month. So, we finally made the plunge and bought a nice 42 inch High Def TV along with a Tivo HD. We had a professional install everything, but he couldn't get the Tivo HD to work. He thought we may have to wait for a new cable box that will come with the High Def service. However, I contacted Tivo customer service and was informed that Tivo HD doesn't use IR blasters and requires a coax cable straight from the wall, not an ethernet cable that runs through a cable box. He advised that I return the unit and get my money back. Are there any other options?
