[mythtv-users] the right way to do tuner priority?

[Brian J. Murrell]

I know there has been much controversy in the past about how to properly
assign tuner priorities and that historically, the only proper way to
influence tuner scheduling choice was simply to add the tuners in the
order that you want MythTV to use them.  Additionally to that, I recall
that there was a way that many people were trying to set tuner
priorities but the reality is that it was not doing what they thought it
was doing.

But I also recall some discussion recently about how tuner priority was
fixed so that one could actually set priorities on tuners and it would
have the expected/desired effect.  I don't recall the details however.

What I am trying to fix is that in a given (2h1m) timeslot this evening,
I have a recording occurring on a digital (clearqam) tuner on a given
sub-channel on a given multiplex (channel "102", subchannel "936") and
then 30 minutes into that recording, there is another show on the same
digtial channel, different subchannel that I want to record.  But rather
than using that same digital tuner, the scheduler is scheduling it to
record on a completely different, analog tuner.

I.e.:

2014-09-29 00:00:03.853011 I  Dancing With the Stars         102-936 WWTI  29 20:00-22:01  2  1  1  A  1 0
2014-09-29 00:00:03.853247 I  Mom - Hepatitis and Lemon Zest       7 WWNY  29 20:31-21:00  1 12 12  A 12 0/-3

Where "WWNY" also exists on 102-77.

In fact, there are other less-than-satisfactory scheduling decisions
being made in that same time-slot:

2014-09-29 00:00:03.853554 I  Scorpion - Single Point of Failure 100-7 CITY  29 21:00-21:59  2  8  8  A  8 0

is also being shown on WWNY at 21:01-21:59 (so starting a minute later
than the above scheduled recording).

Ahhh.  But one thing worth noting is that WWNY, on both analog and
digital have a channel priority of -10, where every other channel's
priority is at 0.  The reason for the -10 is that that is CBS and they
are horrible at keeping to their schedule on Sunday evenings.

TBH, I really only want them de-prioritized on Sunday evenings and not
really all of the time, but MythTV can't handle that.  Not without some
external database fiddling at least.

So maybe the -10 on WWNY explains the Scorpion issue above, but it still
doesn't explain why "Mom" was scheduled to record on a separate analog
tuner when a digital multiplex was already being used at the same time.

And no, I am not maxed out on virtual tuners at that time.

Cheers,
