Got home from work and my daughter tells me the guide isn't working on our DTivo receiver. Everything shows up as to be announced. I checked in the settings, it says program guide info through Sept 3. It made it's last service call on AUg. 31st. I found one thread and did what it said, I unplugged the unit for awhile, about 2 hours. When it rebooted, still shows TBA. Any other ideas on what to try? Nothing else appears to be wrong. All previously recorded programs are still on the hard drive.
