Tonight we watched our first video downloaded from Amazon Unbox straight to our Tivo.
The whole process worked great. Two unfortunate things about the experience though. I had to sit at my home pc to order the movie from the web (although it was very easy). Tivo says they will have "order direct from Tivo" ability in the near future. That will be great.
The other unfortunate thing is the price. It cost about 4 dollars to rent a movie for a day which seems a bit excessive considering the cost of NetFlixs. For the next 24 hours we can watch the film all we want, but after that it disappears.
