Help with re-authoring a bluray with multiple m2ts

[geheim]

Hi,
I'm trying to replace a audio track in a bluray which has the main movie seperated into multiple m2ts files. I tried multiavchd which works somehow, the problem is that I get a resulting disc of more than 80 GB, because it remuxes the multiple m2ts files into a single one for each playlist...

Is there any way to replace the audio track while keeping the "normal" size of the disc??

Thanks for your help in advance!!

Why is the movie split like that? Is it for seamless branching? (Like a theatrical and extended cut of the film)
Replacing the audio on each piece would probably be hard, you'd have to cut your audio up into matching segments and then update every m2ts.
I'm not sure if there's a tool that will do this work for you...

If you only want one version of the film, you could just remux that into a single m2ts file, remove all the little pieces (and forget the other cut of the film) and it should fit.

Thanks for your answer.

Exactly, it is split into parts for seamless branching. It is the BluRay of "Winnie the Pooh 2011". I imported the Disc from the US and try to remux it with German Audio from my DVD for my Kids to enjoy the movie in HD ;)
The discs has three mpls for each different language and the files are split according to the language of text Elements in the movie. Parts without text elements use the same m2ts.

I only need one version of the movie (the english one, but with german audio), while keeping the rest of the disc (e.g. menus) intact. I tried remuxing it with multiAVCHD into a single m2ts and manually deleting the parts I don't need. But then the Bluray won't play anymore... It seems to need all the files, perhaps because it is a BD-J Disc??

Manually cutting the Audio into pieces is too much work, so I hoped to find a tool which could do that.

Any additional ideas??

Thanks!!

When you made a single file version, was it the same PlayList # as the original? If not, rename it to one of the 3, then copy the .mpls file twice and name them the same as the other two PlayLists. That why the Java code will always find the PlayList it wants regardless of what language you might be choosing in the menus.

Obviously make sure the .m2ts file isn't over-writing one that is used somewhere else (like if you use tsMuxer, it'll be 00000.m2ts, but if that file is already a trailer or something on the disc, you will need to rename the .m2ts and the .clpi to another number, and then edit the mpls file to point to the new file name (I just use a hex editor for that, replace '00000' with whatever you rename them to)). And then don't forget to copy the .clpi file into CLIPINF (should have the same number as the .m2ts file). Always a good idea to copy the mpls and clpi files into the backup folder as well, just in case.

As long as the PlayList is there, the code shouldn't care about the m2ts files... You just have to make sure you are copying over everything.

I'm not sure what multiAVCHD might be doing, but just use tsMuxer on the English PlayList, add German to it and remux to blu-ray disc structure, then rename as mentioned above and copy the files into the disc structure... mpls, clpi and m2ts are the only files you'll need. You should be able to keep all existing audio, subtitles and chapters that you want, while adding German, and it should work fine...

Thanks so much!! I did it exactly as you suggested and now it works perfectly!!
Renaming the mpls to the original names did the trick!
Thanks!!
