[mythtv-users] Can't use DVB-T in SVN trunk: "Failed to initialize multiplex options"

Hi all,

I upgraded to SVN trunk (rev 14666) last night, and now I have a
problem with my 2 NOVA-T DVB tuners:

mythtv-setup correctly identifies them and its channel scan works just
fine. However, trying to fetch EIT data,  record a program or watch
LiveTV always results in a black sreen and this error in
mythbackend.log:

DVBChan(0) Error: SetChannelByString(2): Failed to initialize multiplex options

(This happens for every channel, not just #2)

The cards both work fine in other programs, I tested them with tzap
and mplayer and I can get a signal and picture without a problem.

I searched for the error message but couldn't find anything useful in
the list or the web. (One rather outdated hint at
http://www.gossamer-threads.com/lists/mythtv/users/182391 and
http://www.gossamer-threads.com/lists/mythtv/users/288826 which
described the same problem a month ago but got no response.)

Here's some additional info:
As an example, here's the line for channel 2 in the channels table:
INSERT INTO `channel` VALUES (1002, '2', NULL, 1, 'arte', 'arte', '',
NULL, '', '', 0, 32768, 32768, 32768, 32768, 'Default', 0, 1, '', 1,
4, 2, NULL, 0, 0, 0, '0000-00-00 00:00:00', '', -1);

And the line for the corresponding multiplex:
INSERT INTO `dtv_multiplex` VALUES (4, 1, 6144, 8468, 826000000, '0',
0, 'auto', 'v', 'qam_', '8', '1/2', '8', '1/4', 0, 'qam_', 'n', '2/3',
'dvb', 2, '2007-10-16 09:40:07');

Thanks in advance for any help!

Jens

PS:
BTW: Not sure if it's related, but when I configure the cards in
mythtv-setup, I get this  on stderr:
DiSEqCDevTree. Warning: No device tree for cardid 1
DiSEqCDevTree. Warning: No device tree for cardid 2

I  tried the tips in
http://www.gossamer-threads.com/lists/mythtv/users/255314 to get rid
of the warnings, but it didn't help. Still, I'm not even sure if
they're something to worry about with a DVB-T card.
