I was able to get DTS-HD by selecting the exact track. may have just been my error. all is well.

I tried with the version you linked to: ( dtsdecoderdll.dll 1.1.0.1) and no go. no audio at all in MKV file. Blu-ray rip is fine.

strange, MakeMKV is supposed to have an open source DTS-HD decoder?

confused.

I had an old copy of Arcsoft TotalMedia, installed it, registered and copied the dtsdecoderdll.dll (1.1.0.9) to the program files folder, set the path in the options and no audio at all in .mkv from blu-ray rip.

Thanks for any ideas
