You really should have asked your follow up questions in the
original thread you created. You can find your earlier threads and posts by selecting the "Profile" menu option in the forum above, and then selecting "Show Posts".
CORRECTION: The following mostly only applies to the Windows version of MC, not the Mac version. Sorry for the misdirection.Yes. MC can do what you want.
Ripping DVD/Blu-rays to individual chapter files and retaining the 5.1 audio can present some issues. MC can rip DVDs, but can't decrypt Blu-rays, so you will need third party software for that, such as DVDfab or AnyDVD HD. MC can rip Blu-rays if such software is doing the decryption for it. MC can create "Particles" which allow you to play components of one file separately. Read the Wiki article:
https://wiki.jriver.com/index.php/Particles Also have a look at
Swag of Tools for some tools to enhance MC's capabilities.
But once you have individual chapter files, or set up Particles to play the individual chapters, MC can play them, and you can play them individually, or add them to a Playlist for playback.
About the only constraint you will find is if you want to split chapters into individual files, and you want to use MC to do that. The Conversion tool in MC that can be used to split chapters out only produces stereo files. But there may be ways around that, either by using other tools, or other methods. Again, read the Wiki and the Swag of Tools thread.
