I don't like to say I do, but my parents definitely do. They've been "collecting" from a long time. They started on VHS God knows how long ago and now they have, I would say, close to a thousand cassettes. A lot of them are recorded cassettes, though, that don't work anymore. Teenage Mutant Ninja Turtles, James Bond Jr., Loony Toons - all the cartoons of my youth, saved on those recorded cassettes, gone.
Anyway, they started "collecting" DVD's about three years ago, and now we have little over a hundred. Yeah, it isn't as many as most people have, but we like it. I've watched every one of them 1.5 times (on average). Makes for a great past-time.
I'd type them up if I weren't so gosh darned lazy.
