[mythtv-users] DVB - MythTVSetup unable to scan channels

[Mark Smith]

I have a new Myth box which (for the moment) I'm currently setting up one
VisionPlus DVB-T card.

I've managed to get a signal lock using the DVB tools:

[mythtv at Galadriel util]# szap/tzap "BBC ONE"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
reading channels from file '/home/mythtv/.tzap/channels.conf'
tuning to 505833330 Hz
video pid 0x0258, audio pid 0x0259
status 00 | signal 0000 | snr 0000 | ber bfe4b244 | unc 00a7ac19 |
status 1f | signal 3f00 | snr 5000 | ber bfe4b244 | unc 00a7ac19 | FE_HAS_LOCK
status 1f | signal 3f00 | snr 5000 | ber bfe4b244 | unc 00a7ac19 | FE_HAS_LOCK
status 1f | signal 3f00 | snr 5000 | ber bfe4b244 | unc 00a7ac19 | FE_HAS_LOCK

However, mythtvsetup seems unable to scan the channels, despite being given
the correct starting frequency (50583330 Hz):

[mythtv at Galadriel ~]$ mythtvsetup

...etc....

2005-03-16 23:04:31.484 Closing DVB channel
2005-03-16 23:04:31.516 DVB#0 DVB Signal Monitor Stopped

I probably need to go back and check through all of the DVB configuration
again, but does anyone have any ideas?

I've tried manually setting the bandwidth, constallation, trans mode and
guard interval but none of this seems to help.
