Okay, so now we can properly enter DTS-X as an audio format. However, I've found that literally all of my discs that have a DTS-X-track, also have a DTS HEADPHONE:X audio track - a stereo DTS track "that simulates the 3D environment of the audio’s original mixing stage".

So, how do we enter those DTS HEADPHONE:X audio tracks in DVD Profiler? Note that the DTS-X format doesn't let us enter channels, so if we both list them as DTS-X, we can't distinguish between the two...
