engadgetHD has a nice walk thru of Windows 7 Media Center. I have found it to be much better than Vista Media Center. One thing that was great for me was that I always had problems with my Hauppauge 1250 and clear QAM wasn’t available in Media Center.
After installing Windows 7 it recognized the 1250 without a problem and upon setting up Media Center it found the QAM channels and matched them with the guide perfectly. I’m sure your mileage will vary but this was a huge advance from Vista.
