The procedure for this is discussed in the wiki under Howto -> Adding 
Digital Cable Channels.

All of the tuning/testing is done outside myth, with a view to 
determining what channels you *CAN* get from your cable, and what the 
proper parameters are. You can then poke those values into the database, 
or run a scan in myth, and use the front end channel editor to change 
things where necessary. Knowing the channels also allows you to select a 
proper lineup on labs.zap2it.com.
