The S97S has great reviews. But the Faroudja processor is supposedly not the helralded Faroudja on the the legendary Panasonic RP82. Based on some reviews they said to use 720p with HDMI. It came out withthe best DVd picture which is actually the same native rez as the Z3. You can't go wrong with that combo.

If Media Center is still using WM10 I would still go with NVDVD. Last time I played with WM10 or was it WM9 it does not use hardware acceleration in the DVD player. It only had options to use software acceleration. Since the ATI or GForce card have hardware video acceleration why not use it.
