Note that it's 720p resolution, and I'm sure for around the same price you could buy the Blu-ray. Or why not use Netflix to rent it? I don't see the point yet of purchasing such downloads.
720p is good for me and £12.99 is for the latest films . The older films are £7.99 , I know you can rent full 1080p from Zune but i don't have the bandwidth for that only SD content
720p for me is good enough to be honest , the difference to 1080p on a 40ich screen sitting 8 to 10'' away the difference is hardly life changing
That's fine, but again you can buy the Blu-ray for not much more - Amazon have from newest to latest 8.99 to 14.93.
Oh, sorry, noticed you don't have a Blu-ray player. Ok, but afaik you're gonna have to stream iTunes to your telly and you'll need something like Apple TV.
