Dropped Listing

[statsumi]

I had my Tivo set to record the NFL, Chiefs-Cardinals game. Lo and Behold, the game did not get recorded. For some reason the listing got dropped. Can anybody explain how this could happen?
Thanks.

Go to the To Do List and check the recording history to see what happened. If you select the program that you set, you will get the reason why TiVo did not record it.

I've seen recordings dropped from the To-Do list because when I've scheduled them they have a general "NFL Football" listing and then later the listing is changed to something specific (Bengals @ Chiefs, for instance).
