Downmix 5.1 to 2.0 isn't lossless.

You need eac3to with ArcSoft DTS-HD decoder and run:

eac3to your.dtshd output.wav -downmix

Doesn't 5.1 downmix to 2.0 requires phase shift? Or is this necessary only for Dolby sources?

Never with Dolby sources.
With other sources we can't know. Maybe.
Try the two options and select the best for you.

ok. thats a bit of work

you demux the the sound with eac3to.
then you mux the wav with mkvmerge and use there the splitoption "after timecodes". you copy the timestamps from the chapter.txt.
you get the soundfiles and then you demux the mka-files to your.wav
