Okay, so a very generous member sent me a remuxed mkv of the DCP.

The file is 34 GB, so I have decided to wait for the LD audio that should be ready soon, mux it in and either create a new BD with tsmuxer or upload it as the remuxed mkv it is.

Which is more preferred?

Thanks to that very generous member whoever he is!

I'm not familiar with the HD formats. Am I right if assume that an .mkv container can only have one audio track, while a Blu-ray can have many, so you can put in the "original" audio and the LD audio in there too? I'd say go with the Blu-ray then, as if anything is wrong with the LD audio (not in sync or something else) I can still switch to the 5.1 mix.
