I did a google search for perl http cache and couldn't really tell if
it was just a standard module or a standalone application. Are you
thinking I could use it by adding it into the grabber myself, or as
some kind of filter between the grabber and the RadioTimes website?

I see, thanks.

An interesting question, certainly, I can't really help there though
as I don't have DVB-T these days! I assume you aren't trying to use
the NTL DVB-C data?

That clears things up a lot. Thanks.
