Adding an additional Audio-Track to BluRay Structure?

[pio011]

Hello,

I am trying to to the following:

I have an already authored commerical US-"Hollywood"-BluRay. I backed ti up to my HDD. I would like to ad a (foreign) Audiotrack to it.
To to this with a DVD was relatively simple task: demux vob, remux vob, putting it back together with e.g. vobblanker etc.

But how do I do this with a bluray? Is that even possible? I know how to work on single m2ts tracks with TSmuxer. And in the Folder ""BDMV\STREAM"" is the m2ts-movie file. But I suppose that I cannot just do that: remuxing the additional audio-track with tsmuxxer and copy the movie file back in there, can I?

Another thing: Is it yet possible to change the menus for the additional audio track? For this project, it is not necessary, but i woul just like to know :-)

Thanks for your help!

If you want to modify the orignal menus, no it's not yet possible (even for DVD is a time costly and quite complicate procedure).

You can reauthor the BD with multiAVCHD (menus included).

Thanks for your reply. But I don't really get it :-)
Okay, let's forget about changing the menus. I only want to ad an additional audiotrack without changing anything of the bluray structure - and of course keeping the original menus etc.
1.) Are you saying that I shoul remux everything with tsmuxxer to a m2ts file and then put it back to the original bluray rip with multiAVCHD?
2.) Just curious: What would happen, if I would just put the "new" moviefile back into the original stream folder?

1- no, it won't work, since the pointers are displaced - you author a new BD with multiavchd, not modify an existing one. Check http://forum.doom9.org/showthread.php?t=144046 for something that use an existing BD.
2- it might work if the file would have the same size (replace an audio track with another one of the same size in bytes), but no guarantee.

Have you tried multiavchd? -> http://forum.doom9.org/showthread.php?t=143744

Hmmm...thanks again. But authoring a new BR is not an option for me, not now. Sorry.

You are saying that the pointers are displaced, what are the pointers? The Pointers to the chapters? That means, only the chapters would be messed up?

By the way: I have found something: The author of "BD structure edit" seems to have the same aim: Reauthoring a commercial bluray. But the tool doesn't seem to be updated anymore and there's no manual or proof of working. Does anyone have experience with that?

Thank you crl2007 for your guide and your hint!! I will try that and report to, if it worked! But: You said sth in your guide, that you had to run your modified disc through BR-RB to make it work on a standalone?! Is that always necessary?

Please allow me a 2nd question: What would happen, if I'd just remux the new audio track with tsmuxer and put it back to the original (ripped) disc, without doing all the other things? :)

Not all of them, only the 50 GB ones. They are too big and in my country Blu-ray Discs DL are extremely expensive. I've had reports from people who wrote them on 50 gb blu-ray discs that it worked like a charm. BUT, there is a but, not all BD players standalone accept home made ISO's. It's a protection.

You have to do all the things I've said, just that you don't set up the "Subtitles" Tab and instead of a subtitle stream you replace an existing audio one with the one in your language ( the same as I replace an existing subtitle with the one in my language ). It's imperative to have a reference *.mpls and the same number of video stream, the same chapters, as well as a reference *.clpi file in order to keep the menu functional. It's important to rewrite clpi and mpls original files, because they contain certain markers, that could make the video unplayable in some parts due to modifications. The only situation when you don't have to replace the mpls and the clpi files is when you encounter a disc with an integrated IGS Pop-Up menu.
