I already wrote a tv guide application for my 9600 - it downloads listings from a UK TV guide website.

I've just never got around to making it so that I could distribute it to other people (it's too tied into my own config). It's something I keep intending to do - but I never quite find the incentive.

Edit : Just to reply to Barry's comment - I have an EPG on my satellite system, and when I started I also thought the TV Guide was a waste of time due to that. But it's something I wouldn't be without now - it's one of those things that you don't realise how handy it is until you've got it - being able to just look at the pronto screen to see what's on is surprisingly useful.
