Imagine a website where you can download videos at a variety of resolutions. You'd then have a choice of downloading a high resolution video ahead of time if your bandwidth isn't high enough to watch while it's downloading. Or the other option would be to download a lower resolution video. And in either case you could then transfer the downloaded video to whichever device you care to watch it on.
Now imagine if the self-described 'creative' industry could create a legal way to do what I've descrbed. It turns out they're not that creative after all.
