I’ve prepared an example of how to swap audio tracks using IFOEdit. You can find the latest version by doing a quick search on Google.
I don’t personally have a DVD with DTS as the default audio track but what I’ll do is swap the default Dolby 5.1 and DTS round so that DTS plays by default to illustrate the process.
In DVD Decrypter it’s possible to see what audio streams you have available by selecting IFO mode after loading up the DVD. The screen will look similar to this:
In the right hand side, click on the Stream Processing tab and it will show you what streams are available. I have highlighted the streams I’m going to use as examples with green arrows (no prizes for guessing where they came from) Also you’ll notice red numbers on the left of the streams. These are the order in which the streams appear in IFOEdit.
Ok now you have an idea of what we’re going to do, I’ll explain the process in steps.
- Download IFOEdit and run the program.
- Click the OPEN button down in the bottom left corner.
- Navigate to the VIDEO_TS directory of your ripped files.
- Select the VTS_01_1.IFO file and click the open button*
*or VTS_0n_1.IFO where n is the VTS set you need for the main movie
IFOEdit will now display something similar to this:
To avoid confusion, the red “A” in this picture isn’t present in the original program. It’s something I added to point you to the part of interest.
- To the right of “A” you will see VTS_PGCITI. Double click on this and you’ll get a screen similar to this:
- Click on the selection next to “B” and the bottom half of the IFOEdit window will change. You need to navigate down until it displays something similar to this:
The line indicated by “C” is the first audio stream. On the right there is a value 32768 and can be edited by double-clicking on it. What we want to do is swap the values of the first two of these “Audio stream status” entries, so double-click on the first one and enter 33024. Now double-click on the second one and enter 32768.
Nearly there. Click on the first line of the top window and you’ll see the bottom window change to something similar to this:
- Under the section “Title Set (Movie) attributes:” double click on the first audio track and a dialog like this will appear:
Click on the drop down box titled “Coding mode” and select DTS then click on OK. Do this for the second audio track but on the second one select “Dolby AC-3” for the “Coding mode” box.
Click on “SAVE” in the lower left corner of IFOEdit. It will prompt you to save the file as a .BUP; click yes.
Exit the program and then test out your DVD.
All in less than 14 steps as per request!
Hope this helps!
