I have noticed that different channels have different amounts of data 
available all the time.  I use the Vancouver non-digital listings (I'm 
in Burnaby) and have noticed that some channels always go to the end of 
the 14th day and others always end at 17:00 on the 12th day.  Those 
channels with short listings (A&E, DISC) were the ones that broke and 
showed "no data" for several days.  I used myth-setup to clear the 
listings and then ran /etc/init.d/mythfilldatabase manually, and 
haven't had any problems since.  Those channels still run a day and a 
half behind the rest, but they do get fresh data every night.

You could probably just find the location where mythfilldatabase stores
its end-of-listings pointer and roll that back a few days every night
before the normal run so that it gets 3 or 4 days worth of listings at
the far end of the schedule.  I would expect it to fill in the holes and
discard the duplicates....
