Brand new Tivo Premiere XL with Boston based Verizon Fios with M cable card and no tuning adaptor (none is required), ethernet wired to 25MB/s up and down network. Strange issue happening. Tuner 0 can not tune in channels 752 Nick for kids, 554 Spike, 690 Comedy Network, 717 VHI. The odd thing is the frequency for each channel. 554, 717 are both at 861000khz and 752, 690 are both at (855000khz). These are the only channels that can't be tuned in. All channels can be tuned to tuner 1 without issue including 752, 554, 690 and 717. Is this a Tivo issue or a cable card issue.
