Need to prioritise cards/inputs for live tv

I have a system with a DVB-T card and the composite input of an old
analog tuner card connected to a foxtel STB. How do I get the system to
default to the DVB-T card for live tv? It always starts with the analog
card?

I also want to get the analog tuner up and running again, and ran into
the same problem - it looks like this card always takes priority over
the better quality DVB-T card (same channel content). From what I can
see, the only priorities are to do with recording.

Re: Need to prioritise cards/inputs for live tv [In reply to]

I had a problem like this a long time ago, and if memory serves there
wasn't an option as such. The selection priority was at the time
selected by order of adding the card to the database. So you might have
to toss your current card setup and do it again, setting up the DVB-T
card first.

Again, very historical and from memory, so this may not currently be, or
ever have been, true. :) You may wish to wait and see if anyone else has
a better answer.

Nope. Input preference has no impact on live tuner selection.

For live, by default it chooses an available card with the same
hostname as the requesting frontend. If none, it chooses the lowest
numbered cardid that is available. If none it shows a warning message.
The default input for the chosen card is initially used. Pressing
"Y" switches to the next higher available card and wraps after the
highest number. If I have five card and I'm sitting at the host for
card 4 while card 2 is in use, it will pick card 4. "Y" changes to
5. "Y' again goes to 1 and again goes to 3.

If the avoid conflict with the scheduler is checked, it ignores
hostnames and chooses the highest numbered card available. "Y" still
counts up and wraps.

For recording, for a the same showing with the same priority score,
it choose the lowest numbered cardinputid available for the sourceid
of the channel. It there are two single input cards for one video
source, the input on card 1 will be chosen unless there is a higher
priority show already assigned then it will choose card 2. If the
Input preference is higher for cardinputid 2, the showing for card
2 is considered first (priority +1) before the showing on card 1
(priority +0). Therefore the episode wins the spot on the preferred
card 2 before the same showing on card 1 is ever considered.

Re: Need to prioritise cards/inputs for live tv [In reply to]

I am not at the machine to try this: is it possible to just renumber the
cards within the database? e.g, the cardid field in a number of tables.
What else?

Yes, in the capturecard and cardinput tables only. However
it may be just as easy and less error prone to truncate these
tables then reenter the cards and inputs with mythtv-setup.
In either case, make a DB backup first.

Are you sure this works? My two backends seem
to prefer the card that appears second in the list of cards.

In the CaptureCard Table
Card 1 is in master
Card 2 is in slave

Similarly, in the CardInput table
The first Cardinput points to capturecard 1
The second Cardinput points to Capturecard 2

And the first card selected for live tv is capturecare 2 in the slave.

I'd like to reverse that some how....

There is a card priority field that works very well for me. Its in
the setup program.

Positive. Unlike hundreds of other people who pull things out of
their own ass that sound plausible to them then try to pass them
off as the truth, I try to post factual information. Either I know,
find out, or don't post.

Selecting a card for live tv is not the same as the order of
preference for placing shows in the schedule. I find it fascinating
that you chose to reply to part of one of my messages from this
thread but ignored the entire explanation that had just been given.

And I found it utterly astounding you managed to formulate
a snotty reply without reading a single thing I wrote.

Specificically you said:

> For live, by default it chooses an available card with the same
> hostname as the requesting frontend. If none, it chooses the lowest
> numbered cardid that is available.

Yet this is clearly not the case in my example. The slave's tuner
always is selected first for watching live tv.

Needless to say, this throws the rest of your reply
into doubt.

Oops, empty post, sorry.

No, as explained before that priority setting in mythtv-setup
affects recording, not live tv.

Have you selected the option 'prefer recording over live tv' option set?
That's not the exact wording, but it's something like that. If have a
master and slave backend, both with two tuners, and I have that option set
and it always selects the last tuner in the slave backend for live tv, and
the first tuner in the master for recordings. And yes, I too manually
rearranged the tuner cardinput ID's to change mine around a bit (I have
one PVR-250 that is bad and records mangled files, that though watchable,
are not the greatest), so I can confirm that it works.

Would love to find that...

Is it in mythtv-setup or just the regular setup in mythfrontend?

My Mythbackend is also the frontend that I sit at most of the time
and since it reaches out and grabs the slave's tuner first
I end up putting all that traffic on my local network. This hasn't
been a significant problem but its an annoyance I'd like
to clear up.

From Bruce's before and after posts in this thread:
-----
If the avoid conflict with the scheduler is checked, it ignores
hostnames and chooses the highest numbered card available. "Y" still
counts up and wraps.
------

The exact wording in frontend settings:
Avoid conflicts between live TV and scheduled shows.
If enabled, live TV will choose a tuner card that is less likely to have
scheduled recordings rather than the best card available.

Quoting Bruce:
"If the avoid conflict with the scheduler is checked, it ignores
hostnames and chooses the highest numbered card available. "Y" still
counts up and wraps."

He gave you the answer and then you accuse him of not reading your
post properly and not knowing what he's talking about?

Thanks to those who gave the correct answer the third, fourth and
fifth times. What hasn't been said is that the checkbox is in
Setup->TV Settings->General on the first page. This is off by default
so he must have checked it at some point.
