Hi Angela,

This sounds like the programs all have the same seriesid.  Normal
recording rules don't match on just exact titles.  They also match on
seriesid.  This change was made a year or two ago to catch the cases
where broadcasters or producers change program titles for various
reasons.

It's strange, though, that the 'new' recordings only show up at the
last minute.  I'm pretty sure all of the options for showing upcoming
recordings account for the seriesid matching.  Are you using EIT?  My
best guess is that the broadcaster is changing the EIT data either
right before or even after the program starts.  Can you chack the
seriesid for one of the programs before (when it isn't scheduled) and
after it actually records?  To do so, go to the EPG and press INFO
twice.

FWIW, when the seriesid matching was added, we also added a 'This
series' recording filter to allow excluding programs from other series
which just happen to have the same title.  We don't currently,
however, have a complementary 'This title' filter to exclude cases
like yours.  For now, you'll have to use a custom rule to match just
the exact titles you want to record.
