Has anyone seen this before. I have one channel (44.1) that I can't reliably get TiVo to tune to. At least 9 times out of 10 any attempt to choose it from the guide or start a recording gets a blank screen with "Problem with the signal on this antenna channel. Trying again". If I enter 44 on the remote, it searches for a bit but will always tune in the correct channel. I don't understand why it will tune the channel one way but not the other. I checked in the diagnostics by putting 44.1 from the guide on one tuner and 44 from the remote on the other. All the settings were identical except for program lock. I've tried running guided setup over, clear and delete all, pull the power. Nothing seems to work. I've emailed and called tivo support but they have no ideas so far. Any ideas? I'm at the point where I will soon be just calling TiVo to cancel and selling the premiere.
