Amazon Unbox Movies On Xbox 360

There was some question upon the launch of Amazon’s Unbox movie download service if it would be possible to stream flicks to a TV via the Xbox 360. The answer is yes, and Amazon has provided these simple steps to automagically stream purchased content to a 360 from a Windows Media Center PC:

1. Download an Unbox video to your Media Center PC.
2. From the Xbox 360 Dashboard, go to the Media blade and select Media Center. Your Xbox will connect to your Media Center PC.
3. Select “My Videos” and then “Amazon” to see all of your Unbox videos.
4. Choose your Unbox video and enjoy!

So the next question is: Can we stream video from any version of XP using Media Connect or Windows Media Player 11?
