Assuming you're using firewire or analog tuning (with an STB and 
external channel change script), you just need to edit the frequency ID 
for the channel so that it issues the appropriate channel change command.

If you have a digital tuner for MythTV and are using clear QAM capture, 
you have to scan for channels, /then/ map schedules direct data to the 
found-in-scan channels, anyway, so you just map it properly in the first 
place (i.e. put the xmltvid for TCM in the channel that is TCM, etc.).

If Schedules Direct is missing any channels (usually local-interest 
channels that don't report their listings to TMS), you can enable EIT on 
those channels (as long as you don't enable it on any channel for which 
you use Schedules Direct data), but, as I mentioned before, I'd be very 
surprised if your cable co is actually sending any usable EIT data.
