Since you are an expert I will leave that up to you, I just wanted for you to have accurate and up to date information rather than hearsay. You might try a library.
Tivo receives 110 channels from translators in my area. About 85 of those channels should have guide info. Tivo only has guide info for 12 of the channels.
Totally worthless. Before you get a Tivo check the guide.
