Why do I have to return damaged movies before you'll send me a replacement?

When I get a damaged DVD, I am now paying for your mistake, Netflix. You shouldn't take away a slot from my queue because you sent me a defective product. When I report a movie damaged, lost, etc., you should immediately ship me the next movie from my queue -- whether that is a replacement of the same disc or just the next movie in line.

I know that this used to be the case when I had Netflix last year and reported some movies lost. Why did it change? The new system is unfair. Not only am I missing out on another movie rental while I'm waiting for the bad disc to arrive, now I am also giving up a rental so I can return the unplayable movie to you.
