I occasionally have this problem. There is a forum where I can get the
information I need, then I use the following SQL to insert the channel
INSERT INTO `channel` (`chanid`, `channum`, `freqid`, `sourceid`,
`callsign`, `name`, `icon`, `finetune`, `videofilters`, `xmltvid`,
`recpriority`, `contrast`, `brightness`, `colour`, `hue`, `tvformat`,
`commfree`, `visible`, `outputfilters`, `useonairguide`, `mplexid`,
`serviceid`, `atscsrcid`, `tmoffset`, `atsc_major_chan`,
Study this carefully. You need to set the "chanid" based on the encoder
you are using, you'll probably have to poke around in your database to
figure this out.
The next tricky part is the mplexid. You have to look at the
dtv_multiplex table to determine which frequency corresponds to the
desired channel number.
