Advertisements Potentially millions of customers have lost the guide data for some or all of their channels, rendering the tivo service completely useless. The guide is what the tivo service is all about after all. So if you have only lost logos, consider yourself lucky. They face a huge task restoring primary functionality for everyone by adding back the guide data for each individual customer or area of the country. It irks me that the restoration of my service might be delayed by the focus on logos.
