Advertisements Located in Cleveland, Ohio, I just purchased the Series 3 HD at Circuit City. Many thanks to the people in these forums mentioning the 10% off coupon. Just called my cable company (Time Warner) and they coming tomorrow to install cable cards into my TV. However, can I wait until after the technican leaves to activate my HD Tivo? I am not going to be home when they come tomorrow during the day and my wife does not want to get involved. I am hoping they can come install the cards and I can come home tomorrow and just connect the HD BOX. Will this work? Any advice here is appreciated. Please let me know. Thanks.
