I don't watch a lot of films/TV series, so I would totally pay to watch a single TV episode/film. But I'm on Linux, and I don't know how to do that with iTunes, or if it's even possible. Hulu and Netflix require a subscription, which gets way too expensive because I don't watch a lot of stuff, and when trying to purchase an episode on Amazon I'm greeted with the following: > We could not process your order because of geographical restrictions on the product which you were attempting to purchase. Please refer to the terms of use for this product to determine the geographical restrictions. I simply can't find any site that lets me pay to download a movie/TV show episode, so I usually turn to Pirate Bay.
