Is there any detail on the improved duplicate detection.  I found
nothing in the relase notes about this.

( The once per week setting needs to be used with care, since it has
been known for the odd 'double bill' of new showings to occur, which
means you miss one.  Also I had trouble with this when recording
Casualty on Saturday nights.  This show moves up and down the schedule,
and this seemed to confused the once a week algorithm. )
