Problem with DVD Burning
 

Recently I have tried to create a back-up copy of a DVD show. However, whenever I try to create a copy of it, my DVD burning program doesn't allow me to do so.

1) Can anyone recommend me a free software that can enable my DVD burner to burn back-up copies of DVDs?
2) How do I rip videos from DVDs into my harddrive? When I tried using a program to do that the other time, it gave me a format not playable when Window Media Player. Is there any software that can rip videos in more common formats such as avi and mpg?

Any and all help is appreciated lots. Thanks.

If it's video DVD just use DVD Decrypter. Decrypt files on HDD and then use NERO to burn them again.
