Advertisements How long does it take TiVo to correct a line up problem? For the last couple of months, the TiVo schedule has shown my local PBS station as "SIGN OFF" from midnight on Friday until 6 a.m. Saturday morning. This most certainly is NOT true. The only way I can schedule a program being shown in that time block is to go to the web site of my local PBS station, look on their schedule, and then set up TiVo to do a manual recording. A couple of weeks ago I finally submitted a report to TiVo and they responded with a case number (7065825), but that's the last I've heard from them... and the TiVo listing continues to show that time block as "SIGN OFF." Without accurate listings information, the value of TiVo is greatly diminished!
