Advertisements About 3-4 months ago our local Dallas NBC channel 5 changed RF numbers. The TiVo could not cope with it. It no longer recorded the shows nor could you watch it live (unless you punched in the new RF number directly). TiVo support had no solution, but were aware of the problem. The solution, you will not like the answer, is: Do a full Tivo reset that fully reformats the hard drive, doing any thing else that will not work. I know, I tried them all first. Apparently, that original mapping of old RF to channel 5.1 etc. would stay even though I could also map to the new RF and channel 5.1...….it left both 5.1's in the box and the TiVo was not happy; thus the requirement to do the full potato, the full clean/reformat, and set it all up again.
