Also, the PCM file is a WAV larger than 4GB, which I’m honestly not sure how you created as WAV has a 4GB limit.

I converted it to W64 using eac3to, which allows you to mux it into a Blu-Ray folder with tsmuxer. I’m making the disc now so I can’t confirm that it works, but it’s super easy to convert the WAV to W64 for anyone that wants to use the PCM track but can’t get it to work.

Download eac3to and stick it in a folder that has a relatively simple path (mine is D:\Editing\eac3to).

Do the same for the PCM WAV file - it might be a little easier to rename it, too. I renamed it to TFA.wav.

Open up your command prompt and type in the eac3to directory, then the original WAV, then the new .w64, and hit enter and let it run.

For example, here’s what I typed into command prompt:

 D:\Editing\eac3to\eac3to.exe D:\TFA.wav D:\TFA.w64

Basically, the syntax is, first point it to eac3to, then point it to the input file, then designate the output file.

Then you should be able to load the PCM into tsmuxer with no issues.

For some reason, mkvtoolnix can’t see the .w64 and won’t open the .WAV, but you can probably mux it in tsmuxer then remux it back into an MKV with mkvtoolnix once the .w64 is part of an m2ts instead of on its own.
