Disk library solutions?

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 that 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?
