PS2 DVD Editing, Nero

[burnmp3s]

Thanks for replying. I need to copy everything off of the dvd, save it to my HD, replace the music files with my own music files (I know how to do this step fine), and then burn everything onto a DVD. In the end the burned DVD will be exactly the same as the original, but with my modified music files on it. The parts I need help with is getting a copy of the DVD on my hard drive with Nero in a format that I can modify the files with, and then burning all of this onto a DVD.
