Reverse engineer a DVD?
on Jan 9, 2013 at 2:22:53 pm

A client has a DVD. They only need to change 1 word of the audio, but they don't have any of the files used to make the DVD. Is there a way to pull the audio file, make a change, and then replace it back? I don't want to reauthor, just replace assets. Ideas?

Nope! You have to rip it, redo the edit and re-author the dvd.

Yeah, I don't think so.
All the files inside a DVD are interrelated, and inside the VOB beside the Video and Audio information I guess that there is a bunch of metadata. Even if you can make new VOBs with new audio (thats possible) I guess you would screw the metadata that allows the navigation.

It can be done with tools like After Edit and a number of PC DVD editing tools but unless you know the ins and outs of the DVD spec you're going to screw things up.

I did something like this long ago for a distributor who wanted to change out an old logo on 100s of the titles they bought from another distributor

Best to demux the entire discs and redo it from scratch

[Bret Williams] "They only need to change 1 word of the audio,"

Pretty expensive word.

The Mayans screwed everyone, didn't they? They need to replace 2011 with 2013. Just a corporate thing.
