HI! I have been using desktop machine with Windows 7 installed as the operating system in it. I have recently downloaded HandBrake 0.9.4 application that converts DVD to MPEG-4. But the problem is that I am not able to perform the same under Windows 7. It used to work under Windows Xp. It worked fine for someday with my current operating system but not now. Please help me out. Thank you.
