Swapping audio tracks

[AdamP-uk]

I have a disc with DTS audio on and want to swap it for the Ac3 audio track is there a semi easy way to do this ??? , i have the ac3 file ( managed to save it before the disc became totally useless ) and the dvd-r backup with the DTS , and i wanna make a disc with just the Ac3 sound cos the kids don't have DTS so they don't get sound (and i don't want them killing another disc ) I wanna keep all the menus and stuff just remove the Dts and stick the Ac3 in its place... will i need the original Ifo/Bup files aswell ??


Any help greatly appriciated

I think IfoEdit software can do this by taking out the DTS audio (or other audio) and put in (multiplex) AC3/Dolby audio, and then re-author the DVD files. I just have not yet done this.

Search for "audio stripping" or "dvd stripping" in this forum and on Google.com.

will i need the original Ifo/Bup files aswell ??

Yes. All of them. You can use DVDDecrypter or another modern DVD ripper software.

Look on these websites for info:
IfoEdit Guides on this website. Find the word "audio" on the page.
