If you're looking to both freshen up your DVD collection and weed it out, check out SwapaDVD. It's from the same people who run PaperbackSwap. Here's how it works: you post DVDs from your collection that you no longer want. Another member can then ask you to ship them the DVD. You pay the shipping. Then you get a credit and can pick out a DVD from someone else's collection. In that case, they pay the shipping. You get one gift credit for posting your first 10 DVDs. Happy swapping!
