Windows Media Center for Mac?

Hello there. I recently saw the Windows Media Center in action in a PC and thought that it worked very well so I wanted to get it for my Mac. At first glance though, that doesn't seem to be possible. So, I was wondering if any of you had done it or found a good program that works similarly. I'm currently trying to set up Plex, but it's taking forever and at one point froze my stuff in full screen. Thanks!!!!

I'm guessing, the fact it's called 'Windows Media Center' means it isn't available on OS X. You could however boot into windows and use it thought that? In sure if you had a copy of 7, then WMC would come with that?
