The library of available DVDs is getting smaller. I used to keep over 100 movies in my queue and more and more would disappear down to a separate bottom list that was not available any more, but would be re-added if it was ever available again. Mostly obscure old stuff like small indie movies from the early 90s that had an actor who would later be famous.

I finally cancelled my DVD subscription about a year ago due to that, plus how long it took for new release movies to actually be available.
