[mythtv-users] mythtv does not tune to channels

For some weeks now I'm stuck with the problem that 'Watch TV' of MythTV
results in just some static noise (or fixed channel if I've set the
frequency manually first). Pressing '1' or '2' does nothing at all except
showing those numbers as overlay. ChannelUP results the following error in
Mythbackend:
Channel: '' was not found in the database.
Most likely, the default channel set for this input
(2 Tuner 0 )
in setup is wrong
For some reason it does not tune into the startchannel (therefore
channum=''), which has the consequence that the error message follows (I
executed the select query included below manually and it returns no rows,
however with the channum condition removed it returns 1 and 2 as results.
Applying this does not fix the problem however.)
The ivtv driver for the PVR250 does not include any errors in
/var/log/messages that could give a clue.
Any idea how to I fix this?

Your database is most likely setup incorrectly.
