We left Dtv a several months back for an OTA + Tivo solution. All has been working splendidly until about a month ago. Channel 11.1 KNTV NBC now only shows "To Be Announced" for all guide data. I can tune to that channel and watch what's there, which comes in great. But I can't use Tivo to schedule recordings. Anyone else in the Bay Area having this issue? Tivo support has been of no help on this.
