Not sure if this is a bug or if it's the way the thing works, but often I hear of a program I want to record that doesn't show up in the "search by title" list but DOES show if you go in through "record by time/channel"

The most recent example is 'the iron chef' on SBS (sydney).

I searched for it in the "title" list the day after it aired - would that cause it to disappear from the list?
