Well, my Media Center PC is working great now! I built one for Christmas and after many times of trial and error 
while in 
Windows Vista, I was able to getting it running well. The only last complaint that I have is this: It takes somewhere around 3 hours to convert a 1 hour TV show that I’ve recorded and then burn it on a DVD.
But, overall, I’m enjoying Windows Vista and the new interface that it comes with. It’s so easy that even my 8 year old sister can use it. (as you can tell by one of the screenshots).
