Hi!
This message is about mythtv-setup, scanning channels and EIT. What goes wrong
and where (and partly why!)
First base information:
Distribution: Gentoo
MythTV version: 0.20_p12172(19:27:40 03/27/07)
dvbscan (linuxtv-dvb-apps) version: 1.1.1.20070114(19:48:34 04/02/07)
And then what I have done:
#>dvbscan -n -x 0 -t 3 -p -U /usr/share/dvb/dvb-c/fi-HTV
> /etc/vdr/channels.htv.scan
That gives me 25 lines with 5 different frequencies, with line form of
"TV1:274000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_128:512:650:17"
// To empty mysql tables
#>mysql
% use mythconverg
% truncate table chanel ;
% truncate table dtv_multiplex ;
% \q
#>/etc/init.d/mythbackend stop
#>mythtv-setup
--> 5. Channel Editor
--> Channel Scanner
--> Scan Type: Import channels.conf
File location: /etc/vdr/channels.htv.scan
--> Next
--> Finish
// easy way to put EIT working on channels
#>mysql
% update channel set useonairguide=1 ;
%\q
Now, if I close setup-program, start backend, start mythtv I can watch TV but
EPG don't work.. Because at 'dtv_multiplex'-table lines are:
(1, 1, NULL, NULL, 250000000, 'a', 6900000, 'none', 'v', 'qam_128', 'a',
'auto', 'a', 'auto', 0, 'auto', 'a', 'auto', 'dvb', 33, '2007-04-04
20:15:36'),
(2, 1, NULL, NULL, 394000000, 'a', 6900000, 'none', 'v', 'qam_128', 'a',
'auto', 'a', 'auto', 0, 'auto', 'a', 'auto', 'dvb', 33, '2007-04-04
20:15:36'),
(3, 1, NULL, NULL, 162000000, 'a', 6900000, 'none', 'v', 'qam_64', 'a',
'auto', 'a', 'auto', 0, 'auto', 'a', 'auto', 'dvb', 33, '2007-04-04
20:15:36'),
(4, 1, NULL, NULL, 282000000, 'a', 6900000, 'none', 'v', 'qam_128', 'a',
'auto', 'a', 'auto', 0, 'auto', 'a', 'auto', 'dvb', 33, '2007-04-04
20:15:36'),
(5, 1, NULL, NULL, 274000000, 'a', 6900000, 'none', 'v', 'qam_128', 'a',
'auto', 'a', 'auto', 0, 'auto', 'a', 'auto', 'dvb', 33, '2007-04-04
20:15:36');
Where all 'transportid' and 'networkid' are NULL.
OK, EIT can't work without 'transportid'/'networkid' information. Maybe this
can be fixed?!?
OK, next problem and here we found errors...

AFTER this I have:
dtv_multiplex-table: 111 records every frequency have now multible lines
with different OR same transportid. Transportid's variating from 1 to 22.
F.ex. freq 274000000 have now 6 lines with same values but (of course)
different mplexid's.
(5, 1, NULL, NULL, 274000000, 'a', 6900000, 'none', 'v', 'qam_128', 'a',
'auto', 'a', 'auto', 0, 'auto', 'a', 'auto', 'dvb', 33, '2007-04-04
20:15:36'),
(27, 1, 1, NULL, 274000000, NULL, 6900000, 'none', NULL, 'qam_128', NULL,
NULL, NULL, NULL, 0, NULL, NULL, NULL, 'dvb', 33, '2007-04-04 22:18:10'),

NULL, NULL, NULL, 0, NULL, NULL, NULL, 'dvb', 33, '2007-04-04 22:18:11'),
(69, 1, 1, NULL, 274000000, NULL, 6900000, 'none', NULL, 'qam_128', NULL,
NULL, NULL, NULL, 0, NULL, NULL, NULL, 'dvb', 33, '2007-04-04 22:18:12'),
(90, 1, 1, NULL, 274000000, NULL, 6900000, 'none', NULL, 'qam_128', NULL,
NULL, NULL, NULL, 0, NULL, NULL, NULL, 'dvb', 33, '2007-04-04 22:18:13'),
(111, 1, 1, NULL, 274000000, NULL, 6900000, 'none', NULL, 'qam_128', NULL,
NULL, NULL, NULL, 0, NULL, NULL, NULL, 'dvb', 33, '2007-04-04 22:18:14');
Only one line have 'networkid' set and all channels (what are at
channel-table) points to that 'mplexid'-line.
channe-tablel: (only) 12 records (because program crashed) but those channels
have 'mplexid' set to point dtv_multiplex lines so IF I start 'mythtv' EPG
works fine at those few channels what I have after crashed scan.
EVERY TIME when I try to scan with mythtv-setup it inserts more and MORE same
lines to database... Some point you have thousands lines and scanning is
everytime slower and slower.. Of course..
Hopely this looooooong message helps someone to fix something.. F.ex. that,
that program would not insert duplicate line to database... Only UPDATE
lines..
And maybe FIX that scan... So it wouln't crash...
OR make EIT scan work without 'transportid' and/or 'networkid'
IF some developer needs more info/debug... I would happily provide.. Just tell
me what to do and how..
