Using Bob Sorel's great instructions (search "ripping 101") I have ripped about a dozen of my favorite DVD's to hard drive and so far all work great except one. It's a music based DVD called Dreamtheater Metroplis. When I attempt to rip it using Smart Ripper I get tons of block errors and then at about 9% complete Smart Ripper just locks up. I have changed some of the options in teh app but same result every time. Anyone have any ideas...?
