Advertisements HELP, we have spent the last two days struggling with our setup, and talked to two customer service tivo reps who were no help. We have Qwest Digital cable and purchased the dual tuner tivo. We keep getting stuck, and the screen reads LINE UP NOT DETERMINED. One cust. said to return the unit, but the second does the same so its something with the way its setup through Qwest. we have been trying to connect it to the TV with the cable box, and tried it on another tv in the house and get the same thing every time. We are so frustrated!
