how do I rip and burn a DVD file to a blank DVD?
The easiest way to do this would by using ImgBurn software. Just a few simply clicks and DVD cloned.
If you are trying to copy a protected DVD you will end up with nothing regarding files and video content. You will need to decrypt the DVD first using DVDFab HD Decrypter. The application features DVD burning so you can perform all the operations in one window.
For ripping a DVD, you can use the free DVD Decrypter which can remove the copy protection and region code from DVD. But it can't work on DVDs of new copy protection and also it can't convert DVD to other format. So if you can't finish the work with it, you can try to use other software like Leawo DVD Ripper or Aiseesoft DVD Ripper.
