Must be a mistake mastering

I just ran Toy Story 3 to a movie only BD25 and for some reason there was no back channel in the DTSHD audio track.

So I checked it out and reran 36.04 keeping both DTSHD tracks. The movie has 2 DTSHD tracks.

Audio: English DTS-HD Master 7.1 (48 kHz / 24-bit / 5507 kbps)
English DTS-HD Master 5.1-ES (48 kHz / 24-bit / 3998 kbps)
French Dolby Digital EX 5.1 (640 kbps)
Spanish Dolby Digital EX 5.1 (640 kbps)
English Descriptive Dolby Digital 2.0 (320 kbps)

The 1st one and BDRBs default audio file is larger and should be 7.1 audio actually the smaller 3998 kbps file is the 7.1 and the 5507 kbps file is 5.1

Can anyone confirm this or am I loosing my mind, again :confused:

It'll be hard to confirm that mate unless someone has that specific disc. Mine has 7 audio streams.

No this is a weird one, even for me:rolleyes:

Just playing around with it I demuxed the movie and the 1st DTS audio file that is only 5.1 is the bigger file.

Perhaps it is a software glitch. I'm using an Xonar HDAV 1.3 deluxe analog out. Almost all movies give me a back channel, this one didn't I wondered if this happened to anyone else.
