Movies on my HD

Today Blockbuster offers me to download movies to my hard drive, sounds tempting but I shutter to think of the DRM and how it restricts me. DRM is too complicated and there is so much content out there without it, that why bother, costs Blockbuster to implement and me to use, wish we didn't have it. However I like the idea better then streaming how Netflix does it as I often got stuck in the middle of a movie. I just don't see it winning over the convenience of free content out there, encombered content is so much less usefull.
