To back up you movies
1. Use DVD Decrypter to decode the movie
2. Create a folder with the film name and a subfolder called VIDEO_TS the name is very important as this is what your dvd reads. Now use DVD 2 One to convert the film.
3. Use Stomp Record Now Max to make a data disk. Add the VIDEO_TS file and Bob's your uncle
Only thing you need to be careful of is the size of file.
