I am using DVD2OneX 2.3.1 and Snow Leopard 10.6 and dtox opens normally. I am then able to choose from make full disc copy, movie-only, or remaster as usual and choose the file like I normally do. Then it doesn't do anything. The picture next to the options is highlighted like it was clicked and I can still move the window around and do not have to force quit to exit the application. It does not get to the scanning part. I was wondering if anyone else has had this issue and how they resolved it or any ideas.
