Unfortunately, Netflix' DVD strategy seems to be to let the back catalog more or less literally rot away. More and more films aren't available at all or have very long waits.

In all fairness, a lot of movies are available to rent digitally on Amazon. I suspect a lot of people supplement Netflix' crappy movie streaming offerings with purchases/rentals on Amazon or Apple. (Or Redbox for recent films.)

But, yeah, I've definitely had people look at me funny when I admit to still having a Netflix DVD subscription and even buying a DVD once in a while.
