Hope you don't mind I hijack this thread av_phile1

Is it possible to extract tracks from one DVD and put them on another?
I have two DVD versions of
Akira, one with really good video but with audio I don't care for, and the other with horrible video but with "better" audio. Is it possible to extract the video and audio streams I prefer from the different DVDs and combine them into one dvdr? I know the result might be out of sync, but I'd love to try

Thanks!
