Yeah the only with UV is that the licence is limited - unlike itunes, where, one you own the movie, you own the movie.
That's one big reason to hate (as I do) UV. Another is that once you download the movie ('for keeping forever' unlike the online version) then it is only valid on the one device you downloaded to - you can't transfer it from your macpro to your macbookpro. So you have to then wait for another (painfully slow) download of a film that you already downloaded.
Don't believe? Try moving your Sony folder from one machine to another - it won't work. So if in 3 years time, when you licence on UV has run dry, and you upgrade your MBP, you've lost that copy.
A few films have already stopped the downloads eg Jeff Lives at Home. Others just won't let you download eg Spider-Man 2.1.
UV ***** and I hope it dies.
