I was with with ScreenSelect who merged with Lovefilm and I continue to be a member. I think the service is great. The films are turned around really quickly, there's a massive selection and you can reserve films that are still on at the cinemas and get them added to your list when they come out on DVD. I've watched 372 films so far from there and experienced very few problems. Off the top of my head, I can only think of two discs that were unreadable, and when I had a disc or two delivered to the wrong address, they were quick to send me other ones after I had notified them that I hadn't received anything. Nice website too. From my experience, I would highly recommend them.
