Channel lineup has changed, but tivo guide hasn't updated yet...

So as of yesterday Charter has converted to 100% digital which is fine because I get more channels, but the kicker is about 30 or so channels now have been reassigned to new channel numbers. For example H2 was on 726 now it's on 723.



Does anyone know how long it usually takes for tivo to get the updated channel lineup? I really don't want to miss any recordings. I can manually go to the channels by typing them, but tivo doesn't have the channel information or program information. I wouldn't really care but when it affects over 30 channels it kind of sucks.



Thanks for your help.
