One thing to note: if you've got multiple copies of the same channel
getting guide data from different sources (e.g. One on Sky using Sky data
and One on Freeview using downloaded data) you want to make sure the data
from each source is identical for that channel. If your Sky data has "All
New Two and Half Men" and your downloaded data has been sanitised to "Two
and Half Men" then the scheduler will not be able to use those channels
interchangeably when recording that show (unless you've set up a custom
rule). IMO it's best to use a single data source for all common channels.

Yes, turn it off. You can just do "update channel set useonairguide = 0;"
(don't need the where clause). Or do it through MythWeb.
