For the last week one of my local stations announced a change in frequency assignments that required a rescan of available channels. The guide is still mapped to the old frequencies and the new frequencies all appear as "To be announced". For example channel 20-1 changed frequencies and I can view the new the video on the new frequency but the guide is still assigned to the old one. I probably spent about 1/2 hour talking to a Tivo customer service person rattling off the old and new frequency assignments by channel (five that I cared about - I ignored the spanish ones). I've also missed a few recordings because the guide is still obsolete. Is there some way to fix this ahead of time (and what data do I need) or am I stuck with a week of a broken guide?
