Comment (by dekarl@…):

Lets see...
Google hints that you might be in Switzerland.

{{{
Apr 6 11:28:15 HTPC-core mythtv-setup[11341]: E Scanner

}}}
looks like your DVB card is unable to automatically guess one of the
parameters and you have to manually scan one transport and learn the
others from the network_information_section (NIT).

Looking further it appears that you might be on DVB-C with CableCom and
got a welcome letter with a network_id in it.
The manual network_id setting is not yet hooked up to the GUI, see #7486,
which enables MythTV to find the correct NIT and realize that your signal
follows the DVB SI standard.

Ohh, and the channel.conf parser is known broken at the moment, see #7701
{{{

}}}

Looking further it appears that CableCom is only providing CI+ cards, but
no CI cards, which do not work with Linux at all.
Knowing some details on country/provider would help alot as especially
DVB-C providers often need special handling.

Comment (by lars.schmohl@…):

I have a local provider, all channels are unencrypted, except for Teleclub
(NDS).
No transponder has a NIT (except for the Teleclub transponder, which is
unusable).

I have got it to work by manually scanning every transponder.

The other thing is that the internal scanner of version 0.24.2 worked
correctly and the internal scanner of version 0.25 does not.

Comment (by dekarl@…):

So if I understand correctly, the real issue is that the full scan can't
tune any channels anymore due to
{{{
Tune(): Setting Frontend tuning parameters failed.
eno: Invalid argument (22)
}}}
which makes it similar to #8758...

Comment (by Jussi Lehtola <jussi.lehtola@…>):

I am experiencing the very same issue on Fedora 17. I can scan for
channels and that works properly, but the channels aren't added anywhere.

Running
$ mythtv-setup --loglevel debug
I see that the error is

2012-07-07 19:33:14.154926 E Original query failed, but resend with empty
strings in place of NULL strings worked.
DB Error (MSqlQuery):
Query was:

rolloff, bandwidth, sistandard,
tuner_type ) VALUES ( ?, ?, ?, ?, ?, ?,

Bindings were:

I have an 8-year old Terratec Cinergy dvb-c card.

{{{

}}}
While the error only means that somewhere NULL and "" are not properly
handled it still hints at an issue, namely that the SDT could not be
found, leading to sistandard being NULL instead of the correct "dvb".

Jussi, the OP has posted a version string that indicates his version is
newer then [778d8111e]. Can you verify that you have 0.25 newer than March
23rd, too? (output of mythbackend --version)

Also knowing your country/provider would help lots to narrow down the
possible issue. (maybe you need #7486)

Googling your name hints at Finland where the patch from #7486 should not
be necessary based on specs. Unified Requirements of HDTV DVB-C and DVB-T2
digital receiver for Finnish market, 6.3.1:
When IRD locks to the first transmitting multiplex, the IRD shall read
the NIT actual table and install the network and channels accordingly. The
IRD should not scan the other remaining frequencies in the network.

The other issue is that the channels are not added after the scan. (even
though they are scanned wrong they should still be added IMHO)

I suggest to make a ticket for "channel scan in <country> on DVB-C
provider <provider> does not work" or similar so we can track the
different networks in separate tickets.

Replying to [comment:5 Jussi Lehtola <jussi.lehtola@…>]:

I get the same problem on Fedora / RPM Fusion F18 with
mythtv-0.26.0-8.fc18 trying to scan for ATSC channels with Hauppauge
WinTV-HVR-2250 card. Here is the downstream bug I just filed:

I have mythtv-backend-0.26.0-8.fc18.x86_64 on Fedora 18 and I have to same
problem as Jussi has. Country is Finland and Cable operator is DNA, 2x
Terratec Cinergy dvb-c cards . Before this I have had mythtv running for
years without problems, but just updated my hardware and did clean install
for everything and now I am not able store scanned channels in mythtv-
setup. Full scan does not work and when trying to import channels from
scandvb I get the same insert problem with sistandard can not be null.

Comment (by jani.halinen@…):

Same problem with 0.26 in Ubuntu, it'll log "Column 'sistandard' cannot be
null". I tried to change the database column to not null: the error
message went away but the channels don't get saved.

I also tried 0.27 and 0.28, either one will print out error messages about
null columns but they also wont save the found channels.

I'm able to watch television with Kaffeine or VLC on this machine. MythTV
used to work in this setup, before I had to rescan the channels. I'm
located in Finland and the card is: "Twinhan Technology Co. Ltd Mantis
DTV"

I have the same problem on ubuntu 12.04, mythtv v0.25.2-15-g46cab93

How to work-around this problem, until it is fixed?

Comment (by matti.laitala@…):

I did multiple changes to my configuration to get it work. I tried to tune
using both cards and end up removing one of the cards as it appeared to be
malfunctioning (if I remember correctly SNR was significantly lower).
Secondly I used old backup to restore my mythtv installation. Since that
my installation has worked fine. I do not have time or nerves to try clean
install again anytime soon...

It does not sound good.
I moved (live now in a different city) so that my old dvb-t confiduration

Is this already fixed in the developer version?
Is there any work-around?

Comment (by J.Pilk@…):

Your scan has identified several multiplex frequencies. What happens if
you enter one or more of those with the Transport Editor and try the
procedure here?

Comment (by Pfeffer.Code@…):

great - that worked!
I manually added a new transport (mythbackend-setup -> Channel Editor ->
Edit Transports). The data for that I took from channels.conf which I
generated before with scan. Most items to enter are intuitively machted to
the entries in the channels.conf. Only two items I had to tryout:
LP Coderate = 2nd FEC item in the channels.conf
HP Coderate = 1st FEC item in the channels.conf
That means they are entered in mythbacken-setup in the reverse order than
they are found in channels.conf.
After entering a new transport, I clicked on "Channel Scan" and selected
"Full Scan (Tuned)". There I entered the same data again - and the tv
channels are finnaly added.
I repeated this procedure for each frequency an now I have all tv channels
available in mythtv :-)

@J.Pilk: Than you very much!
Pfeffer

Great. I'm glad it worked, although I suspect that you entered more values
than were actually needed.
In future, if you need to rescan, try deleting all channels, but not the
transports, and rescanning 'all known transports' with the 'look for
linked transports' option enabled. It might work.
