DVB-S: lost ability to record multiple channels

Greets again, mythtv-users,

while my struggle with xmltv etc I dropped my setup a few times, deleted
and recreated all cards/sources/channels repeatedly.

What I note now is that I seem to have lost the ability to record
multiple channels from one multiplex.

I followed:

http://www.mythtv.org/wiki/Record_multiple_channels_from_one_multiplex

(dropped all cards, recreated ...)

with rescan of channels but still get msgs like:

2009-09-02 18:38:15.997 TVRec(2): Changing from None to WatchingLiveTV
2009-09-02 18:38:16.026 ChannelBase(2): IsTunable(DVBInput,1) Channel is
valid, but tuner is busy on different multiplex (28 != 44)
2009-09-02 18:38:16.050 ChannelBase(2): IsTunable(DVBInput,1) Channel is
valid, but tuner is busy on different multiplex (28 != 44)
2009-09-02 18:38:16.088 ChannelBase(2) Warning: Setting start channel
'1' failed,
selected to '52' on input 'DVBInput' instead.
2009-09-02 18:38:16.111 TVRec(2): HW Tuner: 2->2

---

I use 2 identical Hauppauge WinTV-Nova-S DVB-S cards.
Multirec worked fine already, I know.

An issue I don't understand in this context: input groups.

How to use them? I choose "Generic" for all of them, when I check back,
mythtv seems to have changed the value to "DVB0" on card 0, and to
"DVB1" on card 1. Might this be related to multirec somehow?

I wasn't able to answer this by googling so maybe you can help ...

Thanks a lot, Stefan

This says that the two channels you are trying to record on the same
card are on different multiplexes.

When re-creating the cards, did you select the Recording Options button
and change the max number of recordings to 2? (Chances are when you go
in there after just creating a brand new card it will say 2, but if you
don't go in there, it won't get set to 2. If you didn't go in there
before, going in now will likely show 1.)

So you say "edit this setting anyway" ? Yes, I checked the setting, but
as you mentioned, it *was* 2 already, so I haven't actually changed it
myself.

Did edit that now, but still can't start a third recording, not via
mythweb or mythfrontend ...

hmm. Really rescan channels as mentioned in the wiki?

Thanks, Stefan

If you have enabled multirec on a capture card, its inputs need to be
in their own inputgroup, i.e. not the Generic group. When you setup
your cards from scatch, this should happen automatically.

Nick

ok ... what I still haven't understood:

Two cards DVB0 and DVB1 ... for each card there are 2
input-group-settings available.

Inputgroup 1 gets automatically set to DVB0 for card DVB0, which sounds
correct.

Inputgroup 2 stays at value "generic" ... dunno.

Doesn't that result in the fact that both encoders(?) on card DVB0 are
in the same inputgroup and therefore blocking each other?

As you see I still try to understand the layers here ...

Thank you, Stefan

Each physical tuner should be in its own inputgroup. So, card 1 can be
in inputgroup "DVB1" and card 2 can be in inputgroup "DVB2". Any
virtual tuners (automatically created when you set the number of
simultaneous recordings on a capture card to a number greater than 1)
are put in the correct inputgroup. You should not have to change the
input group as mythtv-setup will choose the correct one for you
(generic if multirec is disabled, or a new group if multirec is
enabled).

Each physical tuner (one physical tuner per /dev/dvb/adapterx device)
can only tune to a single multiplex at a time. With multirec enabled
the virtual tuners associated with that physical tuner can record from
different channels available on that single mux, but to do so they
must all be in the same inputgroup.

With two separate cards (two /dev/dvb/adapters devices) you can tune
to two different multiplexes at the same time. With multirec enabled
you can record multiple stations on those two multiplexes at the same
time (station from mux 1 on card 1, stations from mux 2 on card 2, for
example). All of the virtual tuners on the first card need to be in
one inputgroup, and all of the virtual tuners on the second card need
to be in a different inputgroup.

If you have virtual tuners on different physical cards in the same
input group, or have the card assigned to the Generic inputgroup, you
will get blocking of inputs and will stop multirec from working as
intended.

Cheers,
Nick

Thanks for the explanation! A lot clearer now to me ...

I think I should be OK with this issue:

SELECT * FROM `inputgroup` LIMIT 0, 30 ;

cardinputid inputgroupid inputgroupname
1 7 DVB0
3 8 DVB1
2 7 DVB0
4 8 DVB1

---

Will have to testdrive that multirec-thing further ...

Any ideas for my other mail with:

2009-09-02 19:20:57.865 DVBChan(1:0) Error: SetChannelByString(1):

2009-09-02 19:20:58.067 DVBChan(2:0) Error: SetChannelByString(1):

2009-09-02 19:20:59.591 DVBChan(4:1) Error: SetChannelByString(1):

?

I even swapped cards now as some thread mentioned cards and pci-slots ...

My next try is to downgrade mythtv and re-run things there.

Until now I ran gentoos media-tv/mythtv-0.21_p20877, I will now go back
to stable 0.21_p19961-r2

errm, left that out ...
tried an older kernel instead, no difference ...

I am rather frustrated already, having started from scratch now for more
than 10 times ...

Would it make sense to start over with one card only, adding the second
after getting things working with the first card? In the end that was
the way I did it back then as I added the second card months later ...

I don't know how to proceed :-( and I do know things worked last week.

What changed?

At first I added this epgdata-grabber, redoing channels etc.
Second change was that I moved the harddrives into a new box, other
cpu/mobo ...

But I assume that mythtv shouldn't care as long as I readd cards from
scratch?

I even recompiled stuff (gentoo, you know).

Still these issues:

2009-09-03 19:20:58.875 TVRec(1): Changing from None to RecordingOnly
2009-09-03 19:20:59.068 TVRec(1): HW Tuner: 1->1

Reverting to kState_None
2009-09-03 19:20:59.476 TVRec(1): Changing from RecordingOnly to None

If someone could help me solve this, I would really appreciate this ...

I will take a look at this possibly later tonight. I am on gentoo as
well and I do have a dvb card that I have setup for multiplex and I
have briefly tested that in the past however I do not use that since
over 90% of my recordings are still analog.

I am not using either of the versions in portage however. I am using
my own vdpau patched version 20744 that is in my overlay.

Thanks, John, for any tests on your side.

I will give your overlay a try before going out for a beer.
My eyes want to fall out already ... ;)

I was able to record 1 show on a multiplex and watch the other on
livetv. Remember I only have 1 digital card.

Encoder 15 is local on jmd0 and is recording: 'KDKA-TV News at 11' on
CBS-HD. This recording will end at 11:35 PM.
Encoder 16 is local on jmd0 and is watching Live TV: 'Unknown' on
RETRO. This recording will end at 11:30 PM.

Also have 2 scheduled programs at once:

Encoder 15 is local on jmd0 and is recording: 'KDKA-TV News at 11' on
CBS-HD. This recording will end at 11:35 PM.
Encoder 16 is local on jmd0 and is recording: '110 (RETRO)' on RETRO.
This recording will end at 11:39 PM.

Thanks for the test, John.

To me it seems as if my system tries to use the wrong encoder.

Right now encoder 1 is recording.

When I try to watch another channel on mythfrontend I get the error:

2009-09-04 10:22:31.651 ChannelBase(2): IsTunable(DVBInput,17507)
Channel is valid, but tuner is busy on different multiplex (11 != 12)

Why not take an encoder on the second physical card, encoder 3 or 4?

Maybe something gets mixed up with the numbering of encoders, I don't
know ...

Greets, Stefan

What a journey ...

Took the effort and changed the hostname (as in the howto) and
reconfigured mythtv accordingly to get things OK with IP adresses etc.

---

As I stare at the logs for days now I also got motivated to solve more
of the issues I see, for example:

2009-09-04 16:18:35.100 Preview Error: Previewer file
'/mnt/media2/1048_20090904161831.mpg' is not valid.
2009-09-04 16:18:35.230 Preview Error: Run() file not local:

2009-09-04 16:18:35.303 Preview Error: Preview process not ok.
fileinfo(/mnt/media2/1048_20090904161831.mpg.png) exists: 0 readable:
0 size: 0

I also have some:

2009-09-04 16:18:32.583 DTVSM(0) Error: Wrong PMT; pmt->pn(171) desired(48)
2009-09-04 16:18:32.668 DTVSM(0) Error: Wrong PMT; pmt->pn(1793) desired(48)
2009-09-04 16:18:32.701 DTVSM(0) Error: Wrong PMT; pmt->pn(764) desired(48)

2009-09-04 16:18:32.768 DTVSM(0) Error: Wrong PMT; pmt->pn(173) desired(48)

these might disappear after a rescan of all transponders (I hope).

So many things ...

---

The good thing: multirec seems to work now at last.
Maybe even since yesterday but now it seems reliable.

I checked it now by watching Live TV, triggering recordings via mythweb,
seems to work now ...

The main suspect here still is the epgdata I grabbed via external
xmltv-script tv_grab_eu_epgdata.

Somehow I have the impression that adding these infos scrambles
*something* in the channel setup, leading to incorrect senders or something.

Right now I have EIT-only and things work OK so far.

So basically I am where I was before subscribing to epgdata.com ... for
sure I will continue to debug things ...

Thanks all so far, a tired Stefan

Don't give up!

Are you doing both a DVB-S scan using MythTV's channel scanner, and
also configuring your grabber through mythtv-setup on the video source
page?

If you are, this could be causing the problem you are having. It is
possible that the channel scanner is configuring one set of channels
(that *are* tunenable, but don't have XMLTV IDs) and then the
configuration of the XMLTV grabber though MythTV is creating another
set of channels (that are *not* tuneable, but do have XMLTV IDs).

Here's a more time-consuming setup method (based on MythTV trunk) to
use when you want to configure EIT and XMLTV listings at the same
time:

1) Configure the XMLTV grabber from the command line, selecting the
channels you want listings for. A config file will be created (check
~/.xmltv/tv_grab_eu_epgdata.conf).
2) Run mythtv-setup and select the video sources page
3) Choose "(Delete All video sources)"
4) Create a new video source (call it "dvbs", this is important for a
later step)
5 Select the eu_epgdata XMLTV grabber as the listings grabber, but *do
not* configure the grabber. Check the "Perform EIT Scan" checkbox.
6) Navigate back to the main menu, and select the Input Connections page
7) Select the DVBInput you want to configure, and on the next page,
associate it with the video source you created above.
8) Disable quick tuning, set the other options (unencrypted/audio
channels) to your preferece.
9) Select the "Scan for channels" button, and carry out a DVB-S scan.
The starting channel for the input will be set automatically, as will
the Input Group. Do not set an Input Priority on the "Interactions
between inputs" page.
10) Open the Channel Editor, and in another window, open nthe XMLTV
config file you created above.
11) Navigate the list of channels in the Channel Editor, and for each
channel you want to use XMLTV listings for, edit the channel. Insert
the XMLTV ID into the "XMLTV ID:" field, and disable the "Use on air
guide" checkbox.
12) When you have configured all of these channels (it can take some
time...), close mythtv-setup
13) copy the XMLTV config file created above to ~/.mythtv/dvbs.xmltv
14) run mythfilldatabase - you should now get listings for all
XMLTV-configured channels, and your DVB-S channels should still all be
tuneable.

Work is being done to allow most of these steps from being eliminated,
so in the future it won't be so hard.

When you have configured your channels with XMLTV IDs, you might find
it useful to export a copy of your "channel" table from the MythTV
database so you have a list of the connection between callsign and
serviceid (from the DVB-S scan) and xmltvid (from the grabber). You
can then create a script to automatically update the XMLTV IDs based
on the service id and/or callsign if you ever need to rescan or start
from scratch again.

Cheers,
Nick

That was an intermediate step, yes.

Another config was to only have a EIT-only-source in mythtv (mythtv not
knowing about the external grabber) and running the grabber "manually"
outside, then doing a "mythfilldatabase --file ...".

But I assume that would cause the same conflicts ... ?

I still haven't fully understood the "--update" option for
mythfilldatabase, btw.

I somehow assumed such conflicts triggered, yes ... especially when
editing the channels I noticed many duplicates etc.

phew ... quite some task again. I will give it a try, but maybe it will
take me until weekend to be able to report back.

Thanks for the howto ...

btw I still have the issue that tv_grab_eu_epgdata doesn't deliver
correct output ... as mentioned in another thread here I reported a bug
to gentoo.org already.

So currently I can only run the grabber on another box ...

I will read through this as soon as possible, thank you!

Right now I am somehow happy to have a somewhat working system up again,
as there are some recordings I would prefer not to miss this evening.

Greetings, thanks for the support, Stefan

ps: is there a way to "speed up" getting eit-data in or is that just a
question of "just wait for it" ?

Running the grabber manually (which is what I still do when mixing EIT
and XMLTV) still requires the channels in the MythTV database to have
XMLTV IDs assigned to them.

When you have configured your channels with XMLTV IDs, you can run
mythfilldatabase --update to update listings data and not affect your
channel configuration. It is also how I run MFDB manually.

I haven't manually configured an XMLTV grabber within MythTV for a
long time, but it always used to create new channel entries for each
XMLTV channel you configure.

Check for differences in the Perl libraries the grabber uses,
especially libwwwperl. This has caused a problem with another grabber
recently. Also, as this is a paid service you could contact epgdata
directly to see whether there is an ongoing issue with the service.

I always ensure that only the channels I want EIT listings for are
visible in MythTV, as this will restrict EIT scanning to their
multiplexes. Other than that, it's really a case of waiting - with
active EIT scanning it's going on in the background so you'll get it
when it's received.

Cheers,
Nick

I had those IDs in there.

Wouldn't that solve the issue??

configure mythtv with eit-only, run grabber externally and pipe the xml
into the database with "--update" ??

That would work (as should configuring MythTV with eu_epgdata and
enabling EIT scanning). However, for either method to work you need
correctly configured channels, and this is the time consuming part.

I could testdrive it by adding some xmltvids into the db ... ?
