OK, perfect; thank you. This should be documented in dvbv5-scan. And we
should have a man page for it.
Cheers,

Hi David,
Well, the initial scan files need to be supplied for dvbv5-scan somehow.
The initial scan files that are maintained in the the git repo I
posted earlier are updated by users who notice differencies. Basically
I and some other users have created scripts that automatically
generate the files for my country, so it's rather easy. I don't know
how it works for other countries.
Anyway, if you prefer to generate the data yourself you can use w_scan
to generate it in DVBV3 format:
w_scan -ft -c FI -x > ~/initial_v3.conf
Then use the dvb-format-convert tool that comes in the v4l-utils package:
dvb-format-convert -I CHANNEL -O DVBV5 ~/initial_v3.conf ~/initial_data_v5.conf
Then you can run dvbv5-scan with this file:
dvbv5-scan ~/initial_data_v5.conf
Alternatively you can skip the whole conversion phase and run
dvbv5-scan with the DVBV3 initial tuning data:
dvbv5-scan -I CHANNEL ~/initial_v3.conf

Ah, thank you Olli -- much appreciated!
If dvbv5-scan expects the initial scan files in the new DVBV5 format, does
that mean that these still somewhat mysterious "initial scan files" have to
be supplied, as in the link to the dtv-scan-tables? How are these "initial
scan files" themselves generated?
Surely there must be thousands of different dvb signal locations -- is
linux-tv going to try to maintain these thousands of scan tables for
download? What do users do when their particular location is not represented
in the dtv-scan-tables.git?
Finally, I'm using gnutv to record television; I imagine it still only
accepts the old format? What's the new alternative?
Cheers,
David

Hello David,
Coincidentally I was just yesterday working with dvbv5-scan and the
initial scan files. dvbv5-scan expects the initial scan files in the
new DVBV5 format. w_scan is not producing results in this format.
The scan tables at
http://git.linuxtv.org/cgit.cgi/dtv-scan-tables.git/ are in the new
format. Some of them are a bit outdated though (send in a patch if you
can update it for your area).
The v4l-utils package also includes tools to convert between the old
and the new format.

Greetings --
How do you actually use dvbv5-scan? It seems to require some kind of
input
file but there is no man page and the --help screen doesn't say anything
about it.
Could we document this? I tried
$ dvbv5-scan
Usage: dvbv5-scan [OPTION...] <initial file>
scan DVB services using the channel file
What is "the channel file"? Maybe the channels.conf file? (I created mine
using "w_scan -ft -A3 -X -cUS -o7 -a /dev/dvb/adapter0/")
$ dvbv5-scan /etc/channels.conf
ERROR key/value without a channel group while parsing line 1 of
/etc/channels.conf
So it knows what it wants -- but what is it? Or is this a matter of dvb
versions, and my /etc/channels.conf is in the older format?
Very mysterious.
Cheers,
David
