Sounds like what Kevin was talking about--where mythfilldatabase runs, 
and listings change, which moves around recordings and such so that 
things are placed differently.

What tuners are what?  In the "not working" --printsched you posted, I 
see the cards 19, 22, 23, 24, 25 in use for various recordings.  Cards 
24 and 25 have channels like 32, 40, 44, etc.; whereas, 19, 22,  and 23 
have ones like 109-63 and 84-77 and 66-112.  Therefore, I assumed that 
24 and 25 are analog cards.  I'm also assuming that 19 and 22 are 2 
physically different tuners--because when it's recording The Office on 
19 and Grey's Anatomy on 22 (both on 109-xx channels), it can't record 
Person of Interest or Whitney (which both air on 84-xx channels).

If that's correct, I'm also assuming that since you have a card 19 and 
cards 22, 23, and 24--with no 20 or 21--and that 19 and 22 were assumed 
to be different physical tuners, that 23 and 24 are both virtual tuners 
on the same physical card as 22.  And, that you either don't have any 
virtual tuners on the physical card with card 19 or that for some reason 
they are not usable.

So, once it assigned The Office to card 19 and Grey's Anatomy to 22 
(first 2 shows in priority order), and Grey's Anatomy had locked the 
physical tuner on 22 to a mux, it had painted itself into a corner.

Of course, this is all guesswork since I don't have any idea what cards 
and inputs you have defined nor how they're defined.

If 19 is multirec capable, you really need to check the multirec 
configuration--as it seems to be broken.  If it's not multirec capable, 
putting it as the most-preferred tuner is likely not what you want--as 
it will basically forego multirec in a large number of cases.

Basically, my recommendation is the capture card portion of 
http://www.gossamer-threads.com/lists/mythtv/users/264034#264034 (and 
then being very careful to re-configure things the way you want/the way 
that maximizes the use of multirec).
