XBMC should do everything you're looking for and then some; plus it's free. Here's the link.

EDIT:
I'm assuming that you're talking about a DVD collection that is on a computer or some other storage device. If you're talking about a physical DVD collection and you're looking for more of an excel spreadsheet type of program, then xbmc isn't the answer for you.
