Not according to the printsched output you posted. The one and only
occurrence of Person of Interest on that schedule is:
2011-09-08 08:13:57.424734 I Person of Interest - Pilot 84-77 WWNY 22 21:00-22:00 2 0 0 A C -3
So, if you're saying there's now a showing on one of your analog
channels, that is probably one of the things that changed that caused
the scheduler to "strangely" schedule/place things differently such that
you didn't need an override--exactly what Kevin was talking about where
more information becomes available allowing MythTV to better optimize
usage of resources. (Of course, before you do add any channel
priorities, please read and understand all of
http://www.mythtv.org/docs/mythtv-HOWTO-12.html because it will have
other effects. :) Adding a negative priority to the Ontario channels
(preferred approach) or a positive priority to the NY channels (a worse
approach of attempting to solve the same problem) will actually mean
that MythTV may choose to record a -3 priority show on WWNY rather than
a -2 priority show that airs only on CJOH.)

How about you post your capturecard and cardinput tables along with the
schedule on your website instead of making me guess at all the possible
different configurations you might have that might make a difference?
:) And, really, based on what you've said above, I'd like to see your
channel table, too.
It may just be that--because you have some, but not all, shows airing at
the same time on the Ontario channels and because it's preferring the
Ontario channels--you just need to put a -1 priority on the Ontario
channels so it will use the New York channels, which have more shows on
the same mux (assuming 84-XX channels are one mux and 109-XX channels
are a separate one).

If you had done that, your capture cards and inputs should all be
starting at 1, not 19. So, it seems you may have done that before, but
have since changed things around?
