I've been using DVD shrink for years and it has performed flawlessly. The last couple of week I've developed a problem. When I start ripping a DVD it starts out fine, then progressively slows down , taking all night to finish ripping a DVD. I don't have an entry in my device manager for ide controllers. I'm running Windows Vista SP2. And don't know why I don't have this controller, but I've checked and googled and can't find a reason why.
