I recently discovered the joys of LPCM soundtracks on VC-1 encoded Blu-Rays. The issue is that VC-1 is a bitch to transcode, so I have to convert the movie to H264. I can do that without quality loss, but the settings required to do that mean a 15 hour transcode on my quad-core i7 laptop. The problem is that the transcoder cannot do pass-thru on LPCM. The only way around that was to use a multiplexer to add the LPCM soundtrack from the first rip to the transcoded copy. It worked flawlessly.
I'm glad I only have a dozen or so movies with this issue, because the processing takes so long that I can only do about one per day.
Here is the process:

Here is the process:
- Rip movie with MakeMKV
- Transcode movie with Handbrake at the same bit-rate as the original rip
- Use the multiplexer function of MKVToolNix to add the LPCM soundtrack from the raw rip to the transcoded copy of the movie.
