Using mythweb is slightly less tedious -- you can at least see all the 
channels at once and do copying/pasting of the XMLTVID from the 
schedules direct website.

I've periodically seen talk of trying to automate the process, but that 
can never be reliable without some sort of data coming from the cable 
provider indicating which channel it is (unless it were a community 
effort...groups of people who have a particular provider maintaining a 
web service that maps xmltvids to the frequencies/programs used by the 
cable company).
