Fair enough. They would have probably sent Jonathan Ross round to sort
me out anyways, so I'll keep quiet.
Out of interest do you know /why/ the Radio Times publishes this data?
My googling just brings up various posts on mailing lists, forums and
blogs about the XMLTV grabber itself. However I cannot find anything
from the Radio Times and/or BBC that mentions the fact that the raw data
is available in the first place.
Is this something that they are required to do for some reason? Or some
trial/beta service that they may scrap/charge for in the future?

I wasn't aware that the grabber did any changing of the data content
beyond possibly dealing with overlapping times or dodgy character
encoding problems. XMLTV was one of those programs I just installed and
let it get on with it without ever learning more about it.
I've been reading through the program and the supplemental files on the
website and I was pleasantly surprised at the amount of cleansing that
is actually going on.

I run Debian's stable release, which has an older version of xmltv that
didn't understand the category re-assigning codes. Which explains why I
wasn't benefiting from those fixups.

I notice that the --debug option gives a huge amount of output - it
mixes pure debugging information (such as the mapping of channel ids and
parsing supplement files) with the output of potential listing
inconsistencies.
Is there a reason for this, or would you be willing to accept a patch
that adds an --inconsistencies option to separate out the two.

I've installed the latest stable version now and subscribed to the
mailing lists so I'll happily provide feedback on any future
inconsistencies now that I know something can be done to correct them.
Thanks for your hard work.
