rufus

Well today i just bought the 300, but my only DvD player is of pretty poor quality; I want to create an image of the Dvd, then mount it with emulation software so i can watch it properly, otherwise i have to put up with broken sound and stuttering framerates. I created an image using the default settings, mounted it, but when i tried to watch it, there was no video, the audio was playing, but not properly. What exactly do i need todo in order to create a functional image of my Dvd with imgburn?
