As far as I know, MC won't read DVD-A from a DVD-A. But it should read the DTS audio track from a regular DVD. I don't use MC to rip DVDs though (I use the Mac version which doesn't have this). I've used DVD Audio Extractor for both DVD-A and DTS audio DVDs and it worked well. In both cases the audio was saved as FLAC (my choice).
I've also used MakeMKV to rip concerts that have a DTS audio track and that worked great, including saving the video.
