IMGBURN (free) makes and writes images. Works in Windows 7.
If your PC came with a DVD burner, it most likely came with a burning program also. Most burning programs (like Nero Express, that came with mine) can copy DVD's also.

I am new to Windows 7. I have been using Windows XP for several years now. I have been using a program called "DVD shrink" to back up my DVDs. Now that I am using Windows 7, DVD Shrink will go through the process of copying the DVD to my hard drive, but will not do the process of writing the movie onto a blank DVD. I am hoping that somebody on here would have some idea how I would go about how I would go about copying it from the hard drive to a blank DVD. I hope you understand what I am talking about. Thank you in advance for any ideas you might have.
