Add/Replace audio track on commercial DVD backup - possible?

[VCDmonger]

I always use DVDDecrypter to rip, DVDShrink to transcode (if the original is a DVD-9) and CopyToDVD to burn. I always get excellent copies that have no problem playing back on various DVD players.

I'm sure many of you have heard of playing Pink Floyd's Dark Side of the Moon to The Wizard of Oz, and I even have a full length DivX of the phenomenon. However, since I have the DVD of The Wizard of Oz, I would like to rip it to my hard drive, add an audio track containing Dark Side of the Moon, and burn to a DVD±R so I can play it back on my DVD player or a friend's DVD player. The catch is, I want to retain all the special features and keep the menu in tact; I do not want a movie-only copy.

I think that maybe one of my outs to accomplish this is the fact that the DVD contains a 2-channel French audio track. I could remove it and replace it with the track that I want. This would seem to me to be an easy way to do what I want, because not a lot of re-authoring would be required. However, I do not know this for a fact. If you would be so kind as to offer a suggestion as to how I could go about doing this, and which software would be required, it would be greatly appreciated.

that would easily solve a ton of peoples problems, unfortunetly (as far as im aware) their are no apps that will just allow you to replace the audio (but for video it's the opposite) on a ripped disc. You would have to re-author it.

And if you did try something like this trick, it wrecks the navigation and chapter times, etc, but would stil retain everything

the trick

just re-author (using whatever app--like Maestro) the movie with the audio tracks you want and the one you want to add. Once it is done you would have your movie with all audio tracks you desired.

Next go into the VIDEO_TS folder the app made for this, and take the vob title set from it and replace it in the folder for the ripped disc (making sure the title set name is correct). Then use ifoedit and hit "get gts sectors" resave it and burn. The disc would still work but have some problems (mainly with menus and running times)

It can be done. Here's the thing, there is no way to have a menu button to select the additional audio track unless you re-author the meny as well. Yes you could replace an existing audio track to make the menu work, but my personally suggestion would be manually cycle through the audio tracks using the 'audio' button on your remote.

Here's how it works. You do need to re-author the VTS of interest, then splice it back into the original DVD file structure. Take a look at:

http://www.doom9.org/mpg/maestro2.htm

you only need to worrk about the last 1/2 (no need to re-encode with CCE). Here's an outline of the process:


1. Demux ac3 audio stream of interest from Pink Floyd DVD.
2. Rip the entire Oz DVD to you HD
3. Find the VTS with the main movie (hopefully 1 PGC)
4. Demux to m2v and all needed ac3 files (subs if needed)
5. Run chapter extracter on VTS
6. Re-Author everything in new VTS
7. Re-name new VTS to match old, delete old, replace with new, run IFOUpdate to fix pointers/sectors
8. Burn the VIDEO_TS folder

So the basic idea is to delete the original VTS, replace with a new VTS that your authored with the additional audio stream, then use IFOUpdate to fix all the IFO files. You then burn the new hybrid VIDEO_TS folder to a DVDR.

Again there will not be a button to select this stream on the main menu. You can create one by editing the main menu but that gets a little more complicated. If you're truely interested, I was once able to do this (project for fun) but it took a LOT of trail and error, several programs and really getting to know IFOEdit

Luck...

thats the same method i mentioned and in the end the running time and a few other things depsite what i had done before hand were still screwed up

Thank you for the replies! I am somewhat familiar with DVDMaestro (thankfully) and I finally had time to sit down today and give this a shot. I got to step 7 in Vejita-sama's instructions (also I followed the Doom9 DVDMeastro guide) from this thread. When I updated the IFOs in IFOUpdate, I got the PGC error, which made me then realize that I'm an idiot because I didn't realize I was working with a multi-PGC title sooner.

I could not find a multi-PGC guide for DVDMaestro, does it not support it? Perhaps someone knows of a multi-PGC guide for DVDMaestro... please post a link if you do! Thanks.

Well, as an update I thought I'd let you guys know what was going on. I decided to use Adobe Encore DVD to reauthor and let me tell you, it is a great program. I am very familiar with Adobe products, namely Photoshop and Premiere, and Encore is just as great. Menu creation is very powerful, yet easy to use. I created a professional looking DVD (honestly, it looks professional) in just a couple hours! I made an audio selection menu so I can pick between my Dolby Digital 6-channel or my Dark Side of the Moon MP2 track (which was surpisingly simple to synch with the movie). I also made scene selection menus.

I am having a couple of problems, however. The main movie is 1:41:48 long, but whenever I attempt to demux the VOB from my DVD (which I have decrypted and saved as an image which I mount to a virtual drive) I get an .m2v file that is only 58 minutes long! That happens no matter which method I use, DVDDecrypter stream processing, VOBrator, DecodeVOB, etc. What I ended up having to do was use stream processing in DVDDecrypter to rip just the video as a .VOB and import that into Encore, which worked.

Now I have a new problem. When creating chapters, I got to a point at 0:46:37 into the movie where the video just starts becoming all garbled (multi-colored artifacts), but the audio continues on fine. The video and audio become out of synch for the duration of this garbled mess, then at 0:49:43 everything synchs back up, and the video is fine for the rest of the movie. If I play the exact same VOB in PowerDVD it is perfect!! Anyone have any suggestions?

My guess about the VOB is that Encore uses it's own MPEG-2 codec that is perhaps buggy. I will try to compile the DVD and burn to a DVD+RW to see if it plays fine in my DVD player. If not, I will re-rip the VOB and import it into my Encore project and replace the one that is there. I would rather work with just an .m2v file though. I don't expect many people to be too knowledgeable about Encore since it is still relatively new and very expensive, but any help would be greatly appreciated.
