I'm having an odd issue with my TiVo. It caused me to clear and delete everything and start over but the problem isn't better, it might be worse. I am trying to view channels 7.2 mostly which I believe is RF channel 19. The TiVo scans 7.1, 7.1*, 7.2, 7.2*, etc. There is guide information for 7.1, and 7.2 but if I tune to those channels it is unable to view them. If I tune to the 7.2* I can view the channel just fine. I'm confused by this. Some DTV channel sites show this channel should be easy to receive from my location. I believe I'm 13 miles from the tower. I have a rooftop Mohu Sail antenna that is supposed to be Omni-directional but I have it pointed nearly directly around 228 degrees which is where most of the towers should be. I have about 25 to 30 feet of RG-6 coax from the antenna to the pre-amp that came with the Sail. Any help would be appreciated.
