DTS:X is not always detected as such #5

Hi, I came across a blu-ray disc (American Made 2017 EUR region) in which the English DTS:X track is not detected as being such, while the DVDFab included bdinfo detects it. I made a sample for you. Can you have a look?

Here's the same disc on the DVDFab version:

Oh, and the English 2.0 DTS (2nd track in the list) is supposed to be DTS Headphone:X according to the menu of the disc.

Thanks for the sample. The stream has very high bitrate, so the buffer was not big enough. Should be fixed now.

As for the DTS Headphone:X track: I have seen such type of streams previously, but was not able to get the DTS:X Metadata from them, neither MediaInfo does (which usually is a great tool to get all the info from files). It seems to be a normal stereo track with HRTF related coding, like Dolby Headphone.

Nevertheless, I'll put it on my todo-list, maybe one day I will find a way to detect such streams.
