It's a non-reversible conversion since it's going from floating-point to fixed-precision audio, which also places additional restrictions on playback; HDMI is now required for multichannel tracks rather than S/PDIF.
You can argue that the difference is going to be inaudible - because that's true. My concern is not about audio quality.
But if we're being technical, the conversion to PCM is not a lossless one. The conversion from the resultant PCM file to FLAC is a lossless one though.
 
When it also strips out the chapter information and inflates the file size 5x, I see no reason to recommend it.
To be clear though: only AC3/DTS audio is affected, which mainly applies to DVDs and not Blu-rays.
It's also a quick and easy way to pull audio out of a video file without leaving the program. I'd prefer than it remuxed the audio into an MKA file instead of converting it though. It's much faster, and the original quality.

Has anyone noticed that the OP has an unanswered question? I would answer it but I don't have any DVD-A disks to test this. Everyone seems to have gotten sidetracked arguing technical minutia and have not answered the new forum member's question(s).

Louis: We're normally better than that in welcoming someone to the forums, but sometimes people are really passionate about their audio and get sidetracked. :) I'm sure someone will help you out shortly.

Posts 3 and 4 answered his question as far as I understand. This one can do it too: https://www.videohelp.com/software/DVD-Audio-Explorer

It's not a conversion, it's a decoding step.  The loss was made when the studio encoded it into DTS/DD, not when we play it back.

I feel for the OP - simple Q turns into ... whatever this "discussion" is.

In Summary:  MC supports a wide range of Audio codecs.  If MC can play it, it can convert it.  If MC can not play it, it can not convert it.  Try it and see what you think.

In particular, If you want to convert the MLP on a DVD-A then you will need some of the 3rd Party Tools (mentioned above).  If you want to convert the DD/DTS on a DVD then you are good to go.  You can of course use 3rd Party Tools for the job as well if you prefer their workflow.
