I have a few recommendations if you plan on building a XP MCE PC. An AMD 64 3000+ and maybe a DFI nForce4 Ultra-D or you can go nForce3 if you've got the video card. Hauppauge PVR-150 * 2. 2x512 value ram. NEC 3520 DVD. Spend the extra cash for a nice case that will look good with your home theater if it is going to be in there with your other components. I have a similar setup and if I were to do it again, I would probably spend more on a nice case, though I had a case from my first try at a HTPC that I used instead.
