I dont mean to sound rude or insult but if you werent clever enough to use anon's or my brief instructions Just go to your local PC store ... and purchase a copy of NERO (they are probably selling 9) and it will probably set you back 30 euros but if your willing to waste money on dual layer dvd's to burn one movie onto a disc i dont think a once off price of 30 euros will kill ya
now instructions
1. INSTALL NERO
2. PUT IN KEY FOUND ON/IN BOX TO REGISTER
3. CLCIK ON NERO ONCE ITS DONE
4. CLICK ON NERO VISION
