The concept is interesting but needs to mature more. I've tried a service like this a couple years ago, can't remember the name of it. All the files used DRM and they didn't look as good as DVD because of compression (a movie came out to a 900MB download or so). I think I heard Disney is also starting something like this. The selection is small and the average user isn't going to want to wait 30-40 minutes for a 90 minute movie to download, then either sit at their computer to watch it or go through the hassle of spending more time transferring it to a portable device with DRM.
