Burning a DVD with different audio

[TheNiceGuy]

I have a few older Japanese DVDs, some doubles. Some have English audio/subtitles, and others Japanese audio/subs. And the video quality varies.
Is it possile to say, take a DVD with good video quality, replace just the audio track with that from a different DVD with better audio, and burn a new DVD?
How can I do this?

Thank you.

you need to re-author the dvds. You'll have to rip both dvds and using the dvd author program you can just put video a w/ audio b. You're likely to have sync problems though. check out doom9 guides

Thank you. I'll do a search.
