How long do recordings stay in the 'recent' list?

[time_lord]

Hi, sorry if this has been asked before... How long do recordings stay in the 'recent' list? I've been away for a couple of weeks and only the most recent recordings (6 days old) appear, but I know there are some recordings further back.
Is there some threshold (number of days?) after which recordings are not considered recent? And if so, can this be changed? (I don't mind hacking the db if necessary).

Cheers

Its controlled by the <WhatsNewDayCount> setting in config.xml.
