Not according to the data you had at the time you created schedule.txt
. You had a showing of Person of Interest on 84-77 WWNY , but none on
any of the analog channels.
Granted, it could have recorded The Office, Grey's Anatomy, and Person
of Interest on the digital tuner as long as it used the 84 mux--but
since it had already placed 2 higher-priority shows (The Office and
Grey's Anatomy) on the 109 mux with the Ontario channels and the Ontario
channels didn't air Person of Interest, it got stuck because the it
couldn't move one show at a time to resolve the Person of Interest
conflict--it would have had to move both shows (The Office and Grey's
Anatomy) to the same mux with Person of Interest, and I'm guessing it
doesn't try that hard (because then it's getting to far too many cases
to test when it tries moving everything to each possible showing).
That said, please do send me the data from your channels. If what I
think is happening is happening, there's a way to fix the UI to allow
you to fix the problem without causing new problems with channel
priorities. (Basically I think it will require the same additions to
the setup UI that allowing you to reconfigure your Live TV capture card
and your recording input preferences will require, so--given proof--I
can put it on the list. I'd like to see your channels configuration,
though, to prove it.)

Thus my post:
which says to use "Delete all..." and then provides additional links:
Why the "Delete All" approach?
What's different about the "Delete All" buttons?

Then you didn't use Delete All (or used "Delete all capture cards on
If you have it configured properly--and it sounds like you may--it's not
a big deal, but it makes it a lot easier to verify that things are
configured properly (especially for someone who's reading --printsched
output with no other information provided) if everything starts at 1 and
there are no holes in the ID numbering.
That said, I don't see any reason why it would use card 19, then skip to
card 22 (ignoring 20 and 21) unless there were some input priorities or
a "Preferred Input" on a rule or something changed the order of inputs
in your cardinput table so that the virtual input order no longer
matches the virtual tuner (card) order (as virtual inputs are always
created with virtual card and virtual input order aligned). So, you may
want to redo the capture cards, anyway. Note, also, that if you do
/only/ "Delete all capture cards" (and not "Delete all video sources"),
you won't have to rescan channels or anything--you'll just re-create
capture cards (in the order you want Live TV to use them) and re-connect
inputs (in the order you want recordings to use them--which /may/ be a
different order from capture card/Live TV usage order).
