Yeah, I was hoping for a legal equivalent. I've only dabbled in torrent and haven't been happy with consistency of results. Plus, maybe I'm too honest, but I like the idea of some pennies of my purchase making it's way back to the content creators. Also I'd like to imagine there would be some guarantee of quality this way instead of the free for all you can get in the torrent world.
If nothing like this legally exists, maybe it's a business opportunity? You can choose to download SD or HD, maybe UHD (with audio equivalent) could be offered for a small up-charge.
I'm hoping there's something out there and I just haven't found it yet...
