I don't know if Andrew has any plans - but - just for your info - there is a
commercial offering called DigiGuide (less than 10GBP per year) that
provides UK and Irish channels and can import XMLTV-syntax listings. It is a
fully functional Windows application that also includes teh ability to set
markers (looking out for programmes or text in the description) and taking
actions like voice alert, launch external application (which could initiate
recording on your PC) etc.
I use it and like it a lot and have written add-ons for it.
