why store a disc, which has mechanical playback problems, by the very fact that it has to be played back, when you can access the same file on a hard drive?? I completely disagree with the cost of storage. Nothing in the tech world has fallen in price more than network storage, the same arguements were made for CD's a few years ago, now sales of CD's fall precipitously every year.
As for back up, that gets cheaper too. You can right now, go on line and buy a Drobo with 4TB of completely redundant no hassle, automatic storage and back up in a bundle for a little less than $1000. Next year that will be $500, and 2yrs from now that will be $400 for 10TB. Even without the inevitable file compression developments, that will store a lot of movies, and you won't need an expensive player to play it back.
