Whether it’s episodes you missed or networks (like the BBC) moving towards downloadable programming models, Mivvi can help. Click on ‘Available downloads...’ to start.
Click ‘Configure feeds...’ to set up the websites that Mivvi should monitor. As well as RSS feeds, it will try to examine regular web pages for things that like links about TV programmes. Afterwards, it looks and behaves like the upcoming broadcasts window, except that double-clicking on URLs follows the link.
