device bus encryption capability not detected with an UHD medium

Hey there.

AFAIU, bus encryption is mandatory with AACS2.x(?) an thus with UHDs.

Using version 0.11.1 and an UHD capable drive I wanted to check whether aacs_info correctly identifies BEE and BEC, but it seems it may not. For a UHD it would give:

Bus encryption:
  Device support:   no
  Enabled in media: yes

while on the same device, a non-UHD version of the same movie from a bundle would give:

Bus encryption:
  Device support:   yes
  Enabled in media: no

Is that expected, or why does it not detected the BEC of the device with the UHD medium?

Thanks, Chris.
