So, I am writing an article for work about how the internet has affected our relationship with US TV - like, before it was very easy to avoid being spoiled, but now you have to work at it. Just reading Salon or even the New York Times online can spoil you for a favourite show. So of course I'm mentioning the downloading of episodes and the like, but what I don't know is the actual technology involved in such helpful doings. What sort of hardware is needed to transfer the programme from TV to hard-drive? Is it all terribly complicated? Any techy help would be greatly appreciated!
