Personally, I didn't figure in reused episodes into the equation, but it's around there.
What bugs me is (as I've said either here or somewhere else) they put new TV shows on DVD as soon as they are shot... so usually I check out Tvshowsondvd, and find completely idiotic stuff I've never heard of getting "an Amazing 7th season set" while I twiddle my thumbs waiting like an idiot to hear "Darkwing Duck Vol 3" or something to that extent.
