I just upgraded my Tivo to the 80-hour TiVo® Series2™ DT DVR from the 40 hour series 2. My monthly charge has been 12.95 for the past couple years and I had to buy a new package with the new tivo which costs 16.95 a month. Has anybody else had this experience? I was wondering if you must pay the higher price or if there is a way to stay with your original subscription fee while only upgrading the box. Thanks...
