Hey, I am not sure if any of you care or not but I used to have XP Pro installed on my home machine and with the 360 the only thing I could stream to it would be pictures and music. The music is nice for puzzle games but that is about it. I just installed Vista RC1 (I did have Beta 2 on for a little while before though) and now I finally have an operating system with Windows Media Center installed. I have no WMV files though as most of the video files I download are Divx (for obvious reasons) and I had read that you need to install special streaming software in order to get Divx to the 360. Unfortunately all the software seemed to require the .NET framework 1.1 or something like that and Vista has .NET 2.0 and does not seem to support 1.1. I thought I was sunk but once I actually looked at WMC running on the 360 I noticed that it did point to my Divx files and when I tried them they actually played. Nice. So the long story short (too late) Vista can stream Divx files to the 360 with no special tricks. Just thought you guys would like to know that in case you were worried that when it is finally out it would not support it.
