I'm about 60-70% through a complete overhaul of the existing EPG code to
objectize it so that new layouts and designs can be slotted into an EPG
factory.

If anybody wants a peek at this code, I'll be able to send something by
the end of the week, all being well...

Maybe this will help you guys. I am doing it since I have another EPG
style I'd like to add, but didn't fancy trying to fit it into the
existing EPG code.
