I am planning out a new home theater system and am wondering if there is a performance difference between using the DVD player on my PC versus buying a separate DVD player. I would run the PC DVD output through the S-Video or DVI out (which is better?) on my ATI All-In-Wonder 9800 Pro. Would this be progressive? I would run the standalone DVD player through component cable, which I have heard provides the best quality. Progressive. Either way, the image will be run through a receiver to the projector, right now I am considering the BenQ PB6100. What is my best option here, taking into consideration I already have my PC and would have to spend extra money to get a standalone DVD player?
