[mythtv-users] Problem getting DVB-T card working - Could not find dvb tuning parameters

[Nigel Metheringham]

I'm working with a new installation of Myth 0.17 on FC3 using the ATRPMs 
builds and working from Jarod's guides.  The capture card is a *K-World 
<http://www.linuxtv.org/wiki/index.php?title=K-World&action=edit>*V-STREAM 
Xpert DTV, which appears to be working OK in that the drivers are doing 
the sort of things expected.

Like some others have posted, after having gone throught he mythtvsetup 
I have a whole batch of channels detected (using a set pulled from the 
UK rt xml, and then a scan of the dvb channels from within mytvsetup).  
However after having done this, when starting mythbackend I get log 
messages of the form:-
  DVB#0 DVB SI Table Parser Started
  DVB#0 Using DVB card 0, with frontend KWorld/VStream XPert DVB-T.
  DVB#0 DVB Signal Monitor Starting
  DVB#0 ERROR - Could not find dvb tuning parameters for transport 0
  DVB#0 ERROR - Failed to get channel options for channel 3.

Trying to switch to live TV in the front end gives a blank screen for 15 
seconds.  The backend meanwhile logs
  DVB#0 ERROR - No PIDS set, please correct your channel setup.
  DVB#0 WARNING - No data from card in 1 second.

The database has tables but no entries for dvb_channels and dvb_uids 
although the dvb_multiplex table is filled.

I'm new at this so an idea where to start sorting this would be helpful.

Thanks
    Nigel.
