Wow, looks like the long-running "Amazon Unbox downloads on your TiVo" rumor is true. The LA Times is reporting an unspecified number of TiVo customers will start testing the service Wednesday.
It's perfect timing, with the AppleTV/iTunes store integration coming out this month and Wal-Mart launching movie downloads today. A lot more people have TiVos already and are likely to be Amazon users, so this seems like a natural fit. No word on video quality, file size, or download times, but I hope to see this rolled out to all TiVo customers soon. [thanks wendell!]
update: here's TiVo's official site for it.
