As Rudy said, they don't generally change these things once they've been
rolled out as it affects all the STB's out there. So please put this up
as a patch (and assign it to me please)

I've been waiting for them to start broadcasting this so I could start
implementing it, but you've beaten me too it.

I'm keen to utilize the information provided to fill in the additional
data fields that are currently only provided by the RT times data,
such as the actors, directors etc. If they follow the TV Anytime spec
that i've seen, it will provide the UK with some very useful EIT data.

Sadly i'm away over Christmas & New Year so i won't have much chance
to test it till I get back.
