Basically, change your line-up on zap2it, save it, run 
mythfilldatabase.  It will have both schedules in there until the old 
data falls off, but if you want to remove that, just truncate your 
program table (I think there used to be a button for this in 
mythtv-setup but a recent post from Michael on this subject in the 
archives dispelled this IIRC) before running mythfilldatabase to get the 
new schedule.
