I've noticed this trend, too. I've been able to snag several movies for cheap compared to how much it would cost to purchase the Blu-ray. Also, since I live in a college town, people sell DVDs and Blu-rays cheap all the time, so I've been able to increase my library that way.

It's very nice to be able to watch the movies without an Internet connection, though. I think that's the main reason I still like to rip and convert the movies myself. Good luck if you ever get around to digitizing your library! Let me know if you need any help!
