Hmm. I like the idea of donating, but if you're going to watch the movie even once more, then it's worth it to keep it, since you've already got them. One option might be to get one of those padded CD/DVD binders and put them in there, to take up less space? I don't know what you'd do with the packages (we still have a box or two of old CD jewel cases in our basement at home), but you could at least stick them in some rarely visited corner...
