Episode titles are embedded into each file’s title property.
Audio:

• English DTS-HD MA 2.0
• Japanese DTS-HD MA 2.0 [*]

Subtitles:

• Signs and Songs
• Full Subtitles [*]

[*] = Default

Note that I always remove the lossy core audio tracks (AC3, DTS) contained in the lossless HD tracks (TrueHD, DTS-HD MA), and/or convert PCM to FLAC, so the remux is always smaller than the original bdmv files,

As usual with Discotek cheaping out, this one is fitted on one BD50, but still
efficiently encoded with x264 and optimal settings within bluray compatibility
constraints IMO.

Other notes:

The interview specials are titled in the video as Japanese signs:
"Kashimashi: Portraits of People Part xxx"
but note that:
Interview #5 Ryoko Shintani (Jun Puu)
is:
Kashimashi: Portraits of People Part 6
and that there is not a part 5 segment

The BD Menu video (BDMV playlist: 00010.mpls) had to be manually reconstructed
by multiplexing 00013.m2ts (static image) + 00014.m2ts (bgm)

update: get the discotek BD… also on AB
