Sorry to confuse you earlier. When using a conventional tuner, MythTV
needs to know 4 (minimum) defined numbers to work correctly when
tuning to a channel:
chanid - a unique number given to any particular channel;
channum - a number you use to label the channel (typically cable/tuner
channel number);
freqid - the channel that the tuner actually tunes to; and
sourceid - a unique number for the recording source the channel is on
You need to make sure that for your tuner input, you have channels
correctly defined in your database (you can check this in mythtvsetup
in channels settings, or in the actual database). If you're happy
looking further at the database, I recommend using phpMyAdmin to check
the mythconverg database for obvious issues (check the capturecard,
cardinput and channel tables). If you do find any and make changes,
remember the backend must be restarted.
Channel numbers therefore, can be defined by you when setting up the
system, to a recognisable number. Channel frequencies however need to
match the station to actually tune in on, and therefore needs to be
correctly input.
I hope this helps to clear up your confusion,
Nick
