you have to rip the dvd first to remove the copyrite protection i sudgest dvd decrypter 3.1.5.0 or smart ripper 2.41.
for dvd decrypter insert dvd in to dvd drive if it auto starts cancell it. start dvd decrypter and select mode/ file ( from top bar )
now go to the box which says destination you will see a folder icon click on this and click on "make new folder" name this folder some thing you will easily remember and i recoment you choose to save the folder to the desktop so you will easily find it.
once done go back to the top bar click edit/ select all, now you will see a dvd icon with a arrow pointing to a hard drive icon ( under the destination box) click on this and the programme will rip the movie to the folder you created.
then you can use dvd2one to compress the movie i recomend version 1.13. once its compressed use a programme such as nero xpress to burn the movie. note if you use nero xpress you dont have to bother messing with audio_ts and video_ts folders as nero xpress does this automatically when it's burning the disc.
dvd decrypter and smart ripper are free programms go here for downloads
