Missing Audio - Not in streams

[calvinc]

Hi,

The DVD in question has a feature from the menu where you can listen to the soundtrack. While listening to each song you can view the chapter its from.

The soundtrack option plays the entire song and without commentary. However when watching the chapters the songs play but some are not complete or have talking over them.

I have extracted every single x80 and x81 stream available from every VOB. Some are duplicates but none have the audio as heard during the soundtrack feature.

Where can this audio be? Is it possible part of the DVD is DVD-A? I've looked at the file sizes and the difference between the DVD size and all .VOB/.IFO/.BAK files is not very big.

vstrip doesnt show any other PCM stream or any other audio types.

Another wierd thing is that when playing the soundtrack option no title or chapter info is displayed, it just starts counting the playing time.

Any advice would be appreciated.
Thanks,
Calvin.

Welcome to the forums, calvinc :)

I'd recommend you re-rip the DVD with DVD Decrypter ( available on Doom9's homepage ), with the Stream Information text file enabled ( it should be enabled by default ). This will give you a nice summary of all the streams on the DVD, and if you need help demuxing or encoding an exotic stream the results of the file will help us help you.

Edit: Rereading your post, I may have misunderstood you. This sounds like a rather unique menu situation, and these sound files may be tough to track down. What DVD title is it ? (perhaps another member of the forum has had some experience with it).

Thanks for the welcome KpeX...

Its a surfing DVD, titled "3 degrees". Does have a rather unique menu structure. Has features such as the mentioned soundtrack option and also a nifty feature whereby you enter a 'secret' code and are able to access certain 'hidden' movie chapters.

I'll try the DVD Decrypter option, other than that is it possible that they may have hidden this audio in another stream? There are a few subtitle streams but as far as I recall the movie doesnt have subtitle options? Will verify though and let you know the results.

Thanks,
Calvin.

The only thing that I can think of that you can do if you cannot find the audio anywhere on the DVD, is to play it back and record through something like totalrecorder. But it's got to be somewhere in there. :p
