You can convert all your physical DVDs into a digital collection and store them in the cloud. Once so stored, you'll be able to instantly watch your films anytime, anywhere on any device. It's not free, and there surely are other services that do this, but one is Vudu, which also happens to be a terrific pay-per-movie/show streaming service.
