I suppose you could write a script that pulls the schedule direct
lineup data using tv_grab_na_dd and compares with your copy
from yesterday to determine if a change has occured.  You
would likely have to do some xml parsing, and probably use the
MythTV bindings to select the lineup and channels that you care
about to avoid false positives.  Probably a useful script to contribute
to the wiki.

It might catch the 'channel nnn is no more, it is has moved to mmmm'
case where channel nnn no longer exists, but it would probably not
catch the 'channel nnn content is no longer TWC, it is now HSN'
(which my local cableco has done in the past as part of their
channel 'rationalization').  But anything is better than nothing.
Good luck.
