Can not rip Bizet's Carmen? Makemkv Bug?

[pisymbol]

I am trying to rip this BR disc:

https://www.amazon.com/Carmen-Blu-ray-E ... 0079IJ0R0/

It is brand new. I can play it using VLC all day long. However, every time I try to rip it using makemkv I get:

001002:0020 LIBMKV_TRACE: Exception: Error while reading input

Debug log attached. Any idea on why this is happening? I've never seen this before. Does not seem to be a medium error.

I had audio set to FLAC but then tried it with Default, same issue. Seems like a bug to me.

So I got it to work but I don't know why....

Basically if I choose just the DTS 5.1 surround track by itself, I can rip it.

BUT, if I ask MakeMKV to rip both the DTS 5.1 AND the LPCM+FLAC Stereo, it fails. Any idea why? (bad mastering is all I can get from the forums so far).

Btw, happened again with another MetOpera BD. If I select FLAC and 5.1 can't rip. Just 5.1 can rip. Wondering if this is a mastering bug or a makemkv one?
