I am new user for Ubuntu. I have updated my OS from Ubuntu 12.04 to (12.10 and now) 13.04. I have a DVD of movies, which works fine in Windows 7, and I am able play the movies, and can see the contents. But when I try that DVD in my Ubuntu, I am getting Blank "DVD-R disk" under device, and when I click on it, it just displays option to burn the disk, not displaying the content, I am not able to see the movies which are there in DVD. Help me resolve the issue
