Time Warner, former Adelphia, Yorba Linda, CA I am the first Tivo Series 3 in my area. At first TW said they would have to experiment with a Series 3 they purchased for the local office. But, since I had a Sat AM appt, they decided to go ahead and sent their best cablecard guy over and learn from my install. Two brand new Motorola CCs were installed per Tivo instructions, after activation /pairing of cards, each tuner was working perfectly, displaying all of my HD channels with proper remapping. Had to rerun guided setup for digital channels. Be sure to reboot a few hours after rerunning setup to make sure your program guides for rest of the 2 weeks get downloaded. Initial download only has about 8 hours of data. 18 hours later, both tuners still working fine, full 2 weeks of program data now stored. Looking good. Maybe I'm just lucky. And the first in my neighborhood.
