i am using a studio av/dv capture card and using studio 9 to capture my movies and make dvds.......now to get the best quality for my dvd.....i have heard that one of the most important things is the caputering.....i have a fast enough computer so processing speed is not the problem.....so studio 9 offers me 2 main ways of capturing my video.......avi..and .mpeg.......but what will give me the optimal results if i am creating a dvd and why is that one better than the other..and what should the other one be used for.............

thanks ahead
