I recently bought the japanese movie audition and want to back it up in a certain way. I know how to back up DVD movies that are over 4.5 GB with DVD xcopy. However in this case I want to have more than 1 audio available. In this movie there is a Japanese audio track and Commentary track that only starts from chapter 18 of the movie onwards. Is there A way I can get both the japanese audio and the commentary track on "1" 4.5 Gb disc?
