Good Disk Library Solutions?

First time submitter fikx writes "How do Slashdotters manage large collections of disks? I'm hoping for a way to manage a large collection of movies that would give me menu type access to the content, and the only consumer device left seems to be the Sony disk changer, which is discontinued. I would have thought that handling disks would have been a solved problem and on sale in many forms, but I guess not. Have Slashdotters found or built solutions? Or has this problem gone the way of the typewriter?"
