Hi again,

I never get udev to set the permissions correctly. Now I have the
following in /etc/rc.d/rc.local

# START DVB-T card
/sbin/modprobe --remove cx88_blackbird
/sbin/modprobe cx88_dvb

sleep 5
chmod o+rw /dev/dvb/adapter0/demux0
chmod o+rw /dev/dvb/adapter0/dvr0
chmod o+rw /dev/dvb/adapter0/net0
chmod o+rw /dev/dvb/adapter0/frontend0
## END DVB-T

It seems to work fine but I would have been more satisfied without that "hack".

To the following issue... I have managed to scan the channels and
created a channels.config and have inserted the data in 'dvb_channel'
and 'dvb_pids' which I think is correct. I had to made it the hard way
since the mythtv scanning finds the channels but doesn't insert them
in the tables.

When starting mythbackend I get this in the console:

[root at HTPC ~]# mythbackend

2005-12-27 23:21:37.575 New DB scheduler connection

and when start "Watch TV" I get:

2005-12-27 23:22:30.982 Changing from None to WatchingLiveTV
2005-12-27 23:22:31.023 DVB#0 Recorder: Card opened successfully

2005-12-27 23:22:34.051 DVB#0 WARNING - No data from card in 1 second.

I have inserted the information as:
# SVT1:626000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:1019:1018:1010
INSERT INTO `dvb_channel` VALUES (19, 1010, NULL, NULL, NULL,
626000000, 'a', NULL, '2/3', NULL, NULL, 'qam_64', '8', '1/2', '8',
'1/8', 'n', NULL);
INSERT INTO `dvb_pids`		VALUES (19, 1019, 'v', '');
INSERT INTO `dvb_pids`		VALUES (19, 1018, 'a', '');

What can be wrong?

PS. I can watch the channels using XINE and channel.conf. DS
