It worked for me. I am running a Small Business Server 2003 and an XP Pro machine. The content is on the server and I have mapped drives for pictures and music on the XP machine as well as Media Connect. The music works fine, but the pictures suck (work but suck). It shows all directories and sub directories together, so no directory browsing. This means all my picture directors are in the "root" folder and many have the same name. I use the directory structures for logical organization, which is gone.
All in all, it looks like MS did a pretty poor job of copying XBox Media Center. Looks like my original version 1 XBox will have to hold the line for media purposes, because this box just doesn't get the job done.
If MS would implament something with the functionality of XBMC on the 360, I'd put one in every room. Since they haven't, I will just buy one. However, since they are loosing $126 per unit, maybe that's what they want. Maybe I will go buy three or four more (after the feeding frenzy is over) just to spite Bill Gates.
