Adding an audio stream to an existing titleset

Actually you have to reauthor your titleset, but I'll explain you how to recreate the original VOB structure and correct the IFOs, so that you'll be able to import this new titleset in your VIDEO_TS and everything (menues included) is going to work.
This could be useful even if you just want to modify an existing audio stream (since audio remuxing isn't supported yet) and rebuild your VOB.

Tools needed:
- IFOEdit
- VOBEdit
- MenuEdit (unregistered version)

1. Open your VTS_??_1.VOB with VOBEdit, click on Demux, check "Demux all Video streams" and "Demux all audio streams", click OK and choose the destination folder. Click "Save".

2. Open your VTS_??_0.IFO with IFOEdit, go to VTS_PGCITI and for each VTS_PGC_? click on File ---> Save celltimes to file.
If your titleset has got only 1 PGC, skip to step 4., otherwise go to next step.

3. Open the first CellTimes.txt with a text editor and append to it the values of the second one increased by the last value of the first *.txt. Append each CellTimes file, increasing its values by the current last number of the first file. Save the *.txt

4. Open IFOEdit and click on DVD Author ---> Author new DVD. Input all your streams (the new audio too) and the CellTimes.txt, select the destination directory and click OK.
Delete the new IFOs, keep only the new VOBs.

5. Open your new VTS_01_1.VOB with VOBEdit, click on "Demux" and check "CellID" and "Demux complete titleset". Click OK.

6. Open these new VOBs with Menu Edit and using "Change ID" reproduce the original VOB/cell ID sequence (you find it in the VTS overview of your original VTS_??_0.IFO). Pay attention: the sequence must continue through the VOBs!

7. Open the first VOB with VOBEdit and click on Edit ---> Join CellVobs files. Rename your new files according to your titleset number.

8. Take the VOBs and put them in your original VIDEO_TS folder overwriting the existing VOBs (it's a good idea to make a backup of the entire folder before you replace the VOBs).

9. Open VTS_??_0.IFO with IFOEdit. Go to VTSI_MAT and increase the number of audio streams in VTSTT_VOBS by 1. Go to VTS_PGCITI and for each VTS_PGC edit the new audio stream status: double click on it and insert a number which is the conversion from hexadecimal to decimal of the stream number followed by 00.
Examples:

Stream     HEX value     Decimal value

  80         8000           32768

  81         8100           33024

  82         8200           33280

Edit audio stream properties in VTS overview. SAVE and close.

10. Open VTS_??_0.IFO again, click on "VOB extras", we are going to do a mock strip. Select "Strip streams","Correct Vob-Unit (Navigation Pack) pointers in VOB files" and "correct original IFOs".
Uncheck "Autocopy menu-files to destination".
Click OK, check all your streams and click Strip it. Let IFOEdit process all your files.

11. Put all these files from IFOEdit in your VIDEO_TS folder and it should be OK! (I tested this method with PowerDVD and DVD Shrink).
