Thursday, Charter came to install the cable cards in my TiVo HD. When the guy saw the TiVo he freaked out. His English was limited, but he made it clear that he only installed CableCards in TVs, not TiVo. He made a phone call to someone. The conversation was in Spanish, but i did hear the word, TiVo, over and over. I guess he was talked into doing the install, because he then started. I showed him the instructions TiVo provided for installing the cards, but he couldn't read them. He clearly was not doing it right. He put both cards in the slots and then went about programming them. The instructions said not to install both at the same timeput the first one in and complete installation, then do the second card. The instructions said that both cards needed separate host IDs. I repeatedly pointed this out to the installer, but he refused to listen and installed them both at the same time. Through this whole process, I had to navigate the menus for him, because he didn't want to touch the TiVo remote. And, I had to pay $35.99 for the install. This was not my most pleasant Charter experience. Bottom line is, both cards have the same host ID. Everything seems to be working fine, but I am wondering if this could cause problems anywhere down the line. Thanks!
