Amazon launched the TiVo integration that is part of their Unboxed video download service. When you link your TiVo account with your Amazon account you get a $15 credit (great move, probably wouldn't have spent the money otherwise) that you can use to try out the service risk-free.

I purchased a movie for my kids and when I got home it was already transferring onto my TiVo. Impressive.

Also, it's a way to catch those movies you missed at the theatre the day they come out on DVD... at a fraction of the cost of the DVD.
