original films are protected.
you need to rip the film to your pc hard drive using a prog called dvd decryptor. you can get it from here

rip the film as an image file then burn it onto a blank dvd.
if the original film is over 4.7gb then it will need compressing after you rip it with a prog like 'dvd shrink'
