I use wishlists a lot and have also noticed this problem a few times.
As far as I can tell I have the same sequence of events happen as you, i.e.
guide data gets downloaded and wishlist programs disappear from the todo list, but for me they come back after a few hours. Like you (during this time) I notice that a search for a program in the guide data reveals nothing although the program is in fact there (verified by using the channelgrid TWP module). My conclusion is that the new guide data gets downloaded and the old index (sometimes or always?) gets trashed and rebuilt. But this takes hours! I can't really believe that this is the way TiVo Inc. designed it to happen, but I also haven't found any other reference to the problem.
Meat, beer, ... what more could a kid ask for? Of course... a TiVo! What were my parents thinking?
