I've been trying to get the DTS tracks from the VIDEO_TS directory of a few DVD-A music titles. I realize that MakeMKV does not work for DVD-A/AUDIO_TS, so to be clear, that's not the part of the disc I'm working with.

My process--which works with most discs but occasionally goes wrong--is to rip everything to MKV, then use AudioMuxer to wrap the DTS data into FLAC, which I can then play via Logitech Media Server, Oppo, whatever. This technique preserves the DTS stream and reliably activates DTS decoders.

The big problem that I have with several discs is that the chapters in the MKV are...weird. All the chapter marks wind up in the first second or so of the file with essentially the entire album as the final chapter. I originally thought the fault was in AudioMuxer and not MakeMKV, but I realize now that when I try to play the created MKVs in VLC, I'm seeing the chapter issue before AudioMuxer comes into play.

Here's an example of what AudioMuxer sees for the chapters created by MakeMKV on the DTS track of Donald Fagen's "Morph the Cat" DVD-A:

Code:
CHAPTER01=00:00:00.000
CHAPTER01NAME=Chapter 01
CHAPTER02=00:00:00.033
CHAPTER02NAME=Chapter 02
CHAPTER03=00:00:00.066
CHAPTER03NAME=Chapter 03
CHAPTER04=00:00:00.100
CHAPTER04NAME=Chapter 04
CHAPTER05=00:00:00.133
CHAPTER05NAME=Chapter 05
CHAPTER06=00:00:00.166
CHAPTER06NAME=Chapter 06
CHAPTER07=00:00:00.200
CHAPTER07NAME=Chapter 07
CHAPTER08=00:00:00.233
CHAPTER08NAME=Chapter 08
CHAPTER09=00:00:00.266
CHAPTER09NAME=Chapter 09
CHAPTER10=00:00:00.300
CHAPTER10NAME=Chapter 10


I have a workaround, but I'm curious if anyone else has ever seen this and/or if there are any ideas about what's happening.

Thank you!
